@@Xeno455 Not if you're applying it to all humans. How can that be offensive if everyone is included, and no superficial group or individual singled out? Creationists in the early 20th Century were offended by the idea we descended from primates on religious grounds, to the point there was a trial, but if people want to be offended by well-established science, that's on them and we can also see in such an example why the idea of holding back speech because it might be "offensive" to someone can quickly become destructive to reason.

@@JET7C0 Alright, a few things. 1: Humans are not even closely related to monkeys. Your "established" science falls flat, immediately. Because YOUR science isn't based on real science. We're not even on the same evolutionary branch. At all. We're both primates, sure. Yet the difference between us is like that of grass and trees. 2: The creationist story that you told was all well and good, but the fact of the matter is that we live in a current socially accepted cancel-culture. I don't like it as much as you, and as an individual I do what I want regardless. That being said, I'm not famous. I'm guaranteed to not get canceled because of that fact. Yet a medium sized youtube channel is literally the perfect avenue for people that do accept it to attack. 3: I never made it a race thing. At all. I said "Someone". Your presumptions are ridiculous and you're arguing against straw men from that point forward.

He makes a great case for his position of a combination of rare Earth and rare intelligence

Yes Isaac is incredible. It really takes a long amount of focused time to understand his arguments though. I've been reading about these arguments for two decades and he somehow still blows my mind with new insights when I really pay attention.

He meant that he has knowledge, or have been learning about the subject, for two decades and Isaac still menaged to impress him. It doesn't take two decades of video watching to understand him :).

Correction. Possible solutions. The fact is we do not know yet why we can have not seen any other intelligence out there. But there are a lot of ideas. And the more we learn the more we can hone in on the right solution by discarding what we know is not true. (Like now we know that there are other planets around other stars and that there pretty common. Go back 50 years and there where still those that though that planets may be extremely rare. Maybe even so rare that only our solar system had them. But now we know that is not true.)

It's been delayed to 2021 now lmao

This conment aged well😉

good news y'all, it finally launched

Von Neumann probes are, frankly, stupid. There's no reason to believe anyone would build them.

You're thinking far to small with regards to the benefits of Von Neumann probes. If you're reasonably advanced you've probably got AGI which you can get to act in alignment with your goals (if not then you've probably been replaced by AGI which are likely to be no less expansionist) then making Von Neumann probes which do what you want and can self replicate without diverging over time in values isn't hard. So given the very possible threat of being subsumed by other more expansionist civilizations and the fact expanding now lets you save more energy for pushing back the heat death of the universe (and you can do computing and thus run minds much faster in the degenerate era: ukposts.info/have/v-deo/iZGeaXiij392yYU.html) there's very compelling reasons for an advanced civilization to expand and for them not to would require them to be extremely authoritarian since you need to be able to prevent any group or even just individual from going off and doing so. It's also worth noting that for a immortal civilization their population is going to increase exponentially, so particularly if they are forward thinking they will probably want to develop some real estate before that becomes an issue in millions of years (or likely less since those factions who breed the fastest will come to dominate future population growth eventually).

@@vakusdrake3224 The Von Neumann idea is for unlimited exploration returning information thousands to millions of years after the deaths of the builders if not immortal. Yours referring to local area exploration at least at this time in Universe history so the probes would be limited in how far out they went if no faster than light travel. Probes also might avoid or stay cloaked traveling though occupied systems.

@@RedRocket4000 I'm actually thinking of the sorts of maximally expansionist Von-Neumann probes, which disassemble nearly every system they come upon to make more Von-Neumann probes as well as to turn the material into other useful stuff and store matter in a form that will conserve it for the degenerate era as previously mentioned. I'm very much not thinking just local area exploration since the probes may well transform nearly everything in that civs future light cone into stuff which is useful to the parent civ. As for being limited to lightspeed that's still pretty rapid over cosmic timescales so you'd expect any civilization we randomly saw to have already "consumed" most or all of their local galactic cluster since they would be unlikely to not have a head start of at least millions of years on us.

@@vakusdrake3224 I'm not completely sure but as population grow goes, after a phase of exponential explotion it's likely that the number stabilizes after some conditions are met. This is already happening here, where develping countries still grow in population atva quick rate while more stablished ones like EU economic core or Japan are below the 2 children per couple (Kurzgesagt video on overpopulation). So, with some global planning, overpopulation is not an issue. For me, the strongest argument for colonizing other planets is to avoid extiction in case some natural or self-induced catastrophe strikes the original home planet.

The universe is 14 billion years old. it's highly unlikely that there are thousands of civilizations EXACTLY as advanced as ours and none of more advanced.

No. There couldn't be. We would have seen them by now. Also, the "fact" is not a fact, just popscience nonsense

I think you missed the point of this guy's comment. Our own search is dedicated to the larger/more advanced civilizations as of right now and we honestly have no way of detecting civilizations at our own level. The same would also be true in reverse, because our own radio signal we've been emitting (since the invention of radio) is so hopelessly diffuse that it would be unlikely any equivalent level species would be able to notice it, let alone decipher it (at any significant distance).

There’s also the notion that perhaps advanced intelligent life is incredibly common. After all, if the universe is absolutely packed full of life, then we have no baseline to compare it to.

Took earth 3 billion years, so that makes sense.

Or even from nothing to unicellular

@@eduardoorvananosarcher4053 From a time scale perspective, nothing to unicellular appeared much faster than unicellular to multi-cellular

Maybe going from non-living to living is the great barrier.

@@rubiks6 So that happened within 1 billions years of the formation of our planet, it took nearly 2 billion more to get from single cell to multi cell

Another factor to consider is that Sun has increased in brightness by about 40% during the development of life on Earth. And yet Earth has maintained similar temperature on its surface during all that time. How did that come to be? Maybe there is some really simple and well-understood reason behind this, but I have not really heard of one. Is this reason somehow unique to Earth, or can it be common to every planet? After all, all stars get brighter during their life, although very small stars brighten up significantly slower. But very small stars exhibit substantial instability in their radiation output. Larger stars, on the other hand, increase in brightness much faster, leaving much less time for life to develop around them. In any case, I'm not an expert in physics not in biology, so I can only throw somewhat blind guesses out there

Yeah, I'm in the same boat. I think that single celled organisms probably are fairly common. The multi-cellular one is probably the biggest 'filter'. And the fact that the dinosaurs could have easily ruled today, if that meteor didn't wipe them out. And they were not the greatest thinkers. I mean, the did rule the earth for over 200.000.000 years. So my guess is: 1. Single cellular life = common. 2. Multi cellular life = extremely rare. 3. Stupid animals = incredibly rare. 4. Intelligent animals = nearly zero chance. 5. Space-faring animals = practically one pr galaxy.

lvl1 multicellular organism lvl2 multiorganism hive lvl3 multihive mind An organism is emergent from cells A hive is emergent from organisms A mind is emergent from hives The third level made little sense stated this way initially, but I had an idea. I googled "hive neurons" and got that as a second result: "A Bee Colony Closely Parallels the Neurons of the Brain". So if a single brain acts sort of as a hive of neurons, a multi-brain entity is not a hivemind, it's a mind of hives. A multi-hive mind. A civilization ... perhaps? One can go from there and develop some rather interesting philosophical concepts. That our higher level thinking is civilized, but the term 'civilized' has a specific meaning there. It indicates that our thinking is not really our own. We haven't created it, merely learned. A quote from a movie that I liked: "Our lives are not our own. From womb to tomb, we are bound to others" I'm bit tired and perhaps not entirely rational at this point, and perhaps I should not write this comment, but maybe someone can see something interesting there for themselves ... just maybe. Disclaimer: I'm aware that analogies are good only up to a certain point. The brain is not actually a hive, it may only resemble it in some ways. Great care is needed not to submerge in bs while following such flashes of ... ideas.

I watched something recently that speculated that Oxidation may be the big eureka factor in biological development. So if the rest of the galaxy is developing anaerobically then we likely have a big head start.

Or not even that. Even with all the time many things dontake sense or aren't solved. Not to mention the fact or we haven't even considered. It's a crapshoot. And the fact that more and more papers are written describing certain parameters have to be just right for life to exist we can probably expect that there are many more factors which determining e the possibility for life to exist will be discovered. Rendering the hypothesis of the rare earth more impossibly rare than before. It's already coming into focus. We are the only life permitting planet in the universe. And once that is realized the next realization will be that development of intelligent life is only possible by the transcendent Creator and His will. After all we are based on a code. And we have mutation correcting codes in our DNA. and no code has ever been shown to arise without intelligent agency. Let alone an error correction code. How do mutations randomly create a code that corrects mutations. And virtually all mutations degrade the genome. And these mutations are shown to be degrading us by 60-100 per generation

Really and whitie just can't under this.

Hope we don't give the Aliens Corona Virus lol

Maybe they're like steroids. We'd be like superman.

It is unlikely that extra terrestrial life forms would find our bodies to be a suitable environment for their survival. This is why different species on Earth are usually not susceptible to the same pathogens. It's usually hard enough to be able to survive in just one species. Of course, there are some exceptions (e.g. corona virus made the leap from bats to humans, HIV made the leap from other primates to humans), but those are the exceptions that prove the rule.

There WILL BE at least someone who doesn't do that! Which means your theory does not prevent us finding aliens

@@PersimmonHurmo yeah I'm sure that's true. But it might explain why things are "quiet" and we don't already have clear evidence of being in the midst of a galaxy-wide cultural explosion. I think it is likely that eventually if it's out there we would notice things. We might not see ships or societies or great works: but there might be ruins or leftover oddities that start to point to a narrative that requires an intelligence at one end. If something like Dark Forest theory is in effect, I would liken our situation as being happy, simple, island people on the shore of our beach, looking out into the ocean for a ship, or even some fish. Now, maybe it happens that those smart enough to be out there are aware of each other but in the midst of a great Cold War. Their ships are submarines, designed to hide from each other. Lesser species such as ours, our existence may be obvious to such beings, but they won't have any reason to bother with us. They could probably slip in and out of our system, gathering supplies or just some gravity boost, with no one knowing better. Or it's just optics and we need better lenses. Maybe it's all quite plain if you knew which of the millions systems to scrutinize closer.

I am inclined to support your latter opinion. Dark Forest theory appears too fictitious to me, as if from a sci-fi book

Well yeah about that...

I would honestly laugh my ass off if we found out one day that life originated on Mars. But before the planet could be transformed into the desert world we see today, a lone rock was blasted off from Mars do to a asteroid impact, carrying that chunk to earth and fertilizing this planet. I mean, they found some Martian rocks in Antarctica not too long ago... We're the Martians, and we succeeded in invading this planet after all :P

Still wouldnt make us aliens, we evolved here. It would make our very distant ancestors aliens.

That doesn't make us not aliens... That just makes us aliens who would have been here a long time if it's true.

ayy

They actually wouldn't even have to actively hide. Just stay quiet and no one will ever notice them.

I like to imagine it's more likely that they're just undetectable because they're not like biological, physical life that we can imagine. After all, it's very likely they're "angels" to us, and we're the "apes" compared to them. They may have completely abandoned this physical substrate altogether. But I admit that's just high speculation on my part. Even scarier, imagine that they're hiding because they know that if they were detected there's a non-zero chance that contact could result in an extinction level event for either them or us. Or far worse, that they might decide just to wipe us out with relativistic weapons before we even detect them and not take any chances. Preemptive genocide in the name of self-defense. After all, when you're dealing with the survival of your entire race ... some people would do it.

That works for not finding life on ONE planet. Limited pond-scum life. But if any of those planets developed interstellar tech at 1% light speed, it takes a million years or so to colonize the whole galaxy. Dyson spheres, star mining, MOVING stars... we see none of this, and nobody has left us a welcome mat. So is all life single-planet? Why?

Listen to @@garethdean6382 . Literally the first person I have found on the internet who understands the Fermi Paradox. 1 million years you can colonise the entire galaxy. Our galaxy has existed for nearly as long as the universe itself. It's 13.5 billion years old! That's a lot of opportunities to colonise our galaxy!

@@jasondenton5432 You do not understand the Fermi paradox.

Gareth Dean The time at 1% the speed of light even assuming instant acceleration to that speed and in deceleration, is 10 million years not one million and that's to just reach from one side of the galaxy to the other. That's not including the fact that you have to essentially travel 100,000 light years in distance diameter, travelling that far in EVERY direction. Now that's very rough and not at all a scientific measurement but gives some idea of the distance. Then you have to slow down and get to any and every inhabitable planet along the way and spend hundreds or thousands of years colonising those before moving on to the next. You could spend 20,000 years on just one or two planets. You also wouldn't head out to most far off planets until you know for sure that they are habitable and if you sent out probes, by the time they get there and send a signal back, your entire civilisation could be gone and dead meaning you never even got off the one or two rocks in your own solar system or the surrounding solar systems. You might not even need to go beyond one or two planets you find and colonise because your population isn't even big enough to warrant it for another 30,000 years or more because you already live on four or five planets nearer you. 1% of light speed is absolutely nothing and I'm pretty sure we have many means at the moment that could actually get us up even faster than that and we'd still all die before reaching our nearest solar system because of radiation in space, muscle atrophy and bone density decreases due to lack of gravity and the fact that we wouldn't have enough food or supplies/resources and money to build a ship large enough to carry enough people to colonise a planet and feed them and hydrate them and stop them from killing each other in transit due to space madness, spending 400 years in space at the 1% light speed value you gave just to reach Alpha Centauri, our closest interstellar neighbour. There'd have to be generations of self sustaining people that don't go mad from lack of grass and wildlife and the sound of wind or water and the feeling of being entrapped on this one way journey. Hell, over such distances, because it would take so long, the entire ship's engines or internal life support systems could easily breakdown killing everyone aboard. You'd also need about 40,000 people for a good range of genetic diversity to get to that one planet to colonise it, meaning either a ship that can hold and sustain that population and much more (kids, grandkids etc.) or many large ships carrying them all (a more viable and safeguarded option) and that's all if you can solve the gravity problem and the radiation problem, feeding problem, water problem etc. To colonise the galaxy would take hundreds of billions of years and due to all the hurdles might not ever be possible and most civilisations would die out long before they get the chance or shortly after they begin.

Jhakaro *Problem 1 - Techological advancement* You're assuming that a technological civilisation that has existed for millions of years could would have the same level of technology and therefore the same problems to overcome as our civilisation that has been around for 100 years. But the biggest problem with your counter-argument is that it assumes the colonisation is a linear process. It starts out slow, but occurs at an exponential rate. *Problem 2 - Exponential rate of colonisatino* Once the first planet is colonised, you have two bases from which to send colonies. Even if every base only sends two successful expiditions you soon have 4 bases, then 8, then 16, then 32, then 64, then 128, then 256, then 512, then 1024, then 2048, then 4096, then 8192, then 16384, then 32768, then 65536, then 131072, then 262144, then 524288, then 1048576, then 2097152, then 4194304, then 8388608, then 16777216, then 33554432, then 67108864, then 134217728, then 268435456, then 536870912, then 1,073,741,824. 30 doublings and you have 1 billion civilisations and that assumes each colony only sends two successful expeditions. The milky way is 13.5 billion years old. Plenty of time for 30 doublings. *Problem 3 - The assumption that the aliens send themselves* Many of the challenges you outlay assume that humans are sent. The Fermi paradox does not require this. It just expect to see evidence of alien civilisations. This can take the form of robotic missions, which could also propagate exponentially if the robots are self replicating. This was mentioned in the video.

Isaac Arthur did, but he came to the conclusion, that the Dark Forest Theory is very unlikely.

@@rafstrayhorn5772 Ok please provide your math below.

That line of reasoning assumes there is some reason not to use abundant and easy to use starlight for energy by Dyson swarms. As it stands, all stars shine away hard-to-imagine amounts of energy, that basically goes to waste from the standpoint of civilizations. Sun alone converts about a million metric tons of rest mass into perfectly usable electromagnet radiation each second. Why would a civilization opt out from that source? There might e reasons, perhaps, it's just it's hard to come up with some. And that keeps people wandering, it seems to me.

that asumtion still falls into what most fremi paradox "solutions" fail at, asuming that all of the supoused civilisations took the same path in their technological advanacement, imagining a couple of them having technologies that are vritualy imposible for as to detect with currrent technologies its one thing, imaging all civilistions having thoes technologies its another

Well if they do exist where are they ? At least one of those civilization will be in the spirit of colonizing the galaxy. We will do so for sure if we survive to reach required tech level. With life extending technology that allows us to live around 1000 years old and space ships that can travel 10-20% of the speed of light it would take us around 1 million years to colonize most of habitable planets in milky way. Our own galaxy is one of the oldest ones in the universe at least 12 billion years old , if we have started colonizing then we could do it 120000 times by now even if we do not advance technologically at all from that point on. We can if fact clam for sure than in the past 12 billion years there was not a SINGLE ONE alien civilization that wanted to colonize this galaxy , because if there was we would see it by now without question. And that is the core of Fermi paradox. Where are everybody ?

+Cristian Verdugo Galaz Depends on how many filters a species need to pass before that point. But I get what you are saying. I'm merely proposing a hypothetical to get a conversation going.

+Pärismaalane I guess we will see for ourselves once we get that far. My point was just to point out that there are a few assumptions we make that could possibly be due where we are technologically right now. There are a lot of unknowns.

Not only is the speed of light slow, but attaining even 10% of it is so difficult even without massive relativistic effects!

But ants still have managed to spread all over the planet and are almost everywhere.

@@pierfrancescopeperoni lol only???? That's a huge number making any light from there very very old.

@@laughingatu3699 "Only" is totally relative. 10^5 is literally nothing compared to the distance of the other galaxies. If intelligent beings can occupy the galaxy in millions of years with serif-replicating robots, and we don't see anything of this, it means two possibilities: A) there is no other intelligent life in the galaxy, or it becomes extinct before being able to produce those robots; B) We are the first intelligent life in the galaxy which will reach that technology. Given that the age of our galaxy is of the order of billions of years, instead of millions, it is very unlikely that we would be the first given that we are not the only ones. So we conclude that we are probably the only ones.

Titan's gravity is also low enough for us to be able to fly under our own power. The temperature on the other hand is cold enough to condense methane.

I wish but unfortunately it is very unlikely, after all it is an astrophysics centered channel not astrobiology.

Only one culture on the earth ever came up with science. If that had not happened, we'd still be in the middle ages, at best, or stone age, like North America and Africa was, or bronze age like South America or Asia.

It depends on when you place the moment were it became inevitable that we ended up being a technologically advanced civilization. Once agriculture is invented, maybe its inevitable that sooner or later a civilization gets to the point of having an industrial revolution.

You're saying microbes are easy without any evidence to back up your claim. We haven't even found microbes yet, it could be that life itself, any live, is exceedingly improbable.

+Michael Bishop _"... or stone age, like ... Africa was, ..."_ Actually, Africa (by which I assume you mean sub-Saharan Africa) skipped the Bronze Age and went straight to iron.

@Michael Bishop I don't know why people think Africa as a whole or sub-Saharan Africa in particular was stone age. Just like there was a time when the Middle East was at the forefront of astronomy and Math(Algebra is an arabic term), believe it or not, there was a time when the West Africans were at the forefront of medical science in particular. In the late Medieval and early Renaissance era they already had inoculations for infectious diseases like smallpox, they could do c-sections and even cataract removal surgery. Also like Michael Sommers said, they were also pretty advanced in metallurgy. In fact their iron furnaces could get hotter than most European ones until the Industrial Revolution

The problem is flat planets are too easy to slip under a door and thus render them undetectable.

We have no idea what shape the exoplanets are, how dare you suggest they are not flat like ours!

Is our planet a flat circle or a flat square ? Or neither ?

But what about the dome with a moon painted on and the lamp going around on tracks we call the sun? It's really snowglobe shape.

XD

true bro

So deep, yet so shallow and without meaning.

We already did. Galileo spacecraft confirmed that earth is a habitable planet teaming with life and with civilisation living on it.

Sad...but true..

And the stupidest comment award goes too.....

Paper Dragon check out Isaac Arthur's video on Rare Intelligence. He explores all the things that need to line up perfectly for something like human intelligence and tech to be possible. Spoiler: there's a lot of them

I agree. There are countless reasons why we haven't found them yet. One of that is communication. Our technology doesn't match the alien civilizations out there. Radio is pretty much a crude technology and advanced civs must have got rid of it for a long time. Another thing that video did not discussed is the possibility that we are the most advanced survivor of an alien civ which are going annihilation. It also did not discussed the possibility of survival of the fittest where complex beings can't defeat the annihilating power of nature or harshness of space. Another is fiction. Advanced civs could be a fragment of literature to something greater than us; the concept of gods, then turned monsters, ghosts, and now aliens. I'm just not holding my breath that we'll find each other within this century.

Well said, and a good way of considering how rare intelligent life may be. Earth has countless little attributes that make it aminable to inteillgent life and advanced civilization, and if it was missing any one of them, advanced civilizations may not have arose. For instance, if flint or chert didn't exist on Earth (and are not common on Earth as it is), early humans would not have had a rock with the right properties to make the hand ax, which was the only tool that hominids had for millions of years and which drove our evolution until the neolithic era. If you add all the unlikely qualites that Earth has to make it friendly to advanced civilization, the chances of finding something similar is extremely rare, even 1 in a trillion could be optimistic. If that is the case, advanced civilizations could be very few and far between.

It's not just the fact that flint was here that drove us to develop technology. There were a whole lot of other factors at play too. Like our weird curiosity that causes us to sail into the middle of oceans we know nothing about. Or our obsession with creating stories that explain the world around us, and getting others to believe them too. All of these things are pretty unique, we don't see dolphins trying to crawl around on land just to see what's up there. We were a pretty stable species that lived a hunter gatherer lifestyle for millions of years, we didn't really have any environmental pressure to develop rocket ships or even agriculture. For whatever reason we were curious enough to try new ideas that sometimes went horribly wrong, and then try them again and again until they worked. IDK if that's very common since we are the only example of a truly "innovative" species on earth.

Thank you for the suggestions and feedback!

I'm not sure what alien you're referring to, but every time I restart the video a new tally gets added to my arm...

I don't think so. If there was one I would have masturbated to it.

This show is so good, it could easily continue to be great without relying on taxpayer funding.

We don't need more advanced technology to colonize the galaxy, just brute force and a lot of time.

Our tech does not allow detection of radio transmissions of a civilization like ours even if it were located on Alpha Centauri. The only interstellar communication that we could build with our tech is some gigawatt laser, but it has to be precisely directed at the intended receiver. We ourselves do not send gigawatt laser pulses into nearby stars, so probably they don't do it either.

Maybe we were the only intelligent society that developed the internet and that's how we passed the great filter, enabling global conscious.

Wow, that makes so much sense

Hahahaaa. Leave them to themselves? We're wiping them out by the dozen each year. I don't like the idea of all civilizations being magically good and not altering the universe one bit. It's like an invisible God who exists only you can't disprove him because everything He does looks natural. It's too perfect.

Curiosity and discovery always has leads to exploitation! I view as the free floating rationale of curiosity. They could be wary and vigilant of other intelligences out there. We may even become a nuisance if we discover them among other things! Alien technology would become an ark of the covenant ( something looted and sought after). they would or will eventually just wipe us out!

Gareth Dean Thats the point...the more conscious your are the more you going to leave things at their place and just let nature take its course. Its our stupidity and arrogance that is disturbing the harmony within the universe.

@@Ging_10 the darwiniian rules of survival will always apply! if we became pests or got in the way of their own expansion, they would wipe us out! they would constantly be under our microscope and we may even start to get touchy feely. there is nothing they need from us

Zoophilia Consultant Am not saying that they wouldnt ever think about wiping is out. Am saying that given our current circumstance there is no need for them to show us they exist. We are still too primitive to handle this kind of truth. Still a large portion of humanity literally believes in 2000 years of fairy tales...what makes you so sure that the Aliens want to waste their energy and time trying to communicate with self centered beings who still kill each other over stupid beliefs?

The Exoplanets Channel Maybe... they already did. I'm lookin at you Mark Zuckerberg

@@robboss4085 You made me laugh so hard! 🤣🤣🤣🤣🤣🤣

Hi is not an alien, he is a lizard. It is something different.

Maybe they are aware of us but we are so insignificant to them. Like us seeing a trail of ants. We don't even bother.

By using the sun's gravitational lens and telescopes at 550 astronomical units, you could scan planets as small as Mercury with quite a good resolution across all the galaxy. It's called Fast Outgoing Cyclopean Astronomical Lens (FOCAL).

There is evidence of life in the universe right here on this very planet. In fact it has arisen on this planet more than once despite numerous catastrophic events wiping out earlier pogress Given other factors and the laws of physics it's difficult to formulate a rational argument that it's not everywhere it that has any of the huge variety of conditions we know this planets DNA has adapted to from thermal vents to rabbits to upper atmosphere bacteria.. however, "knowing" is different from recognizing the overwhelming probability. I would say it thusly: I would bet my last piece of cheese and my entire supply of imaginary drugs in the afterlife that life exists elsewhere in the universe.

Not necessarily THE first, but perhaps part of the first (or second) _generation_ of civilisations to evolve in our galaxy, potentially explaining why there _appear_ to be fewer than you'd expect given the age of the galaxy.

Could be, as in possible, but not probable. People keep forgetting how vast this one galaxy is, and how little and how close and how narrow we've searched so far.

And I'll add, frankly, how unimaginatively we've searched so far.

Or maybe were the only ones who even give a crap about what some other civilization might be doing

I am a strong proponent of the we are "early" theory. The Earth is about 1/3 the age of the universe, and it took a certain amount of time for there to be sufficient metalicity in the gas clouds to form planets where sufficiently complex chemistry necessary for life could occur. This could eliminate many stars which are older than Earth and all stars which are much older. Further, if it took 4 billion years for Earth to develop intelligent life, and almost that long to develop multi-cellular life, that time frame, if "typical," could eliminate most or all stars that are younger than the sun, and all stars with lifespans which are shorter. Yes there are a lot of stars in the galaxy, but in the galactic core, you are so close to so many stars, that the odds of a sterilizing event, or just too much radiation could well rule out most of the stars in the galaxy. If we speculate and say that only K and M class stars of at least 4 billion years in age in this galaxy are the only potential places for intelligent life to arise, and make the assumption that maybe we were just quicker than "average" in getting from lava-ball to multi-cellular biosphere, then we could certainly be first in the galaxy. Any life outside the galaxy is so far away as to be virtually irrelevant, extremely hard to detect, and impossible to reach or communicate with.

Worthy of a chuckle. Then again, there are very few two or three-star systems.

**slow clap**

transfering 'the problem with humanity' to another location is not the same thing as addressing and resolving it. until we can address our self-destructive issues we don't deserve to go anywhere else, because we will just end up doing more harm than good to that new place. there seems to be something wrong with us as a species at a fundamental level. call it egomania, in a word. by an overwhelming majority, human beings seem intellectually and emotionally totally incapable of living in harmony with other species or the environment. and those with the will and resoruces to do most damage of all, inevitably hold most power and inevitably devote all their will and resources to trying to dominate and control the few who try to live otherwise.

Wipes you out not me

people die but if you have many people the species lives on, it's not exporting our problems it's hoping that some will survive. if an super bug or supernova or other extinction level event goes of on earth it's bye bye human race for now. But if we export ourselves to other planets outside our solar system such events won't kill us off. if we settle on mars like elon musk wants to do we would have better odds to survive as species.

A couple problems here. We do not currently have a viable other planet proven to be able to keep us alive. Mars gets a lot of hype, but realistic terraforming is a 10,000+++ year proposition which may actually be impossible without a home base planet to work from (you need generations of stable and flourishing social prosperity to produce the will to accomplish a task like that) so colonizing mars requires the same thing that saving the earth requires. We need to figure out how to treat each other well. Without terraforming the likelihood that humans can survive and flourish on mars becomes vanishingly small. The risk of superbugs developing is vastly more likely in the type of monoculture food production that we would engage in on mars, and the spread of a pathogen would be unstoppable in an enclosed air system. The vast majority of the microbiome that we would bring with us would already be intimately familiar with us from living in our guts and on our skin. Extremely high selection pressure from the constant need to clean every surface within the habitat would exacerbate the “Island Effect” of the already closed system. To avoid the extreme pressure of a tiny biosphere, we could build massive engineering projects, couldn’t we? Domes the size of cities. Unfortunately the best material for the job, given the martian context (no petroleum, no limestone) is steel. Aluminum and magnesium would play a part, sulfur concrete and ferrock could play a part, certainly silicon. But all of these materials currently require hydrocarbon reserves to generate the kind of energy concentration to work. Solar energy could cut it, but the build up to go from what we can feasibly bring to mars and what we would need to make any impact would take multiple generations of engineers. Mars is not a new frontier to be conquered by sheer force of manliness. It would require cooperation and logistics on the same scale as making our own planet safe and secure. We have the technology now to prevent super bugs, and to save ourselves from climate change. These are not someday-in-the-future techniques, we can keep our one and only home safe, and teach the next generation how to care for a planet, which ever planet they choose to live on.

But we would need only two or three more planets for that. Really no point in spreading out over hundreds of planets. Especially when you assume that rich societies tend to have shrinking populations because they don't need children to grow into new workers. Robots can do that.
