That’s a yes from me. But I wanna hear what others think.

    i’m pretty sure that extraterrestrial life exists somewhere in the universe, but i’m also pretty sure that the life on earth is the first conscious life in the millky way galaxy.

    if there were others, they’d probably have developed spaceflight and found their way to us by now.

    That depends. Yes, I believe it is probable that life exists elsewhere in the universe. But no, none of that life is building pyramids in ancient Egypt, abducting cows, or anal probing hillbillies.

    He likelyhood of this planet being the only place in the universe some complex proteins folded a billion years ago is zero.

      But the other planets are probably absurdly far away. The space happens to be expanding as well, so that distance is also growing rapidly. If FTL travel isn’t possible, nobody will ever visit those worlds, and they can’t visit us. Just travelling at 1c or even 1000c won’t be much help either. The distances sure truly vast.

              I would say it’s probably close to zero, depending on what physics actually allows. If FTL travel turns out to be completely impossible, then it’s exactly zero. If some sort of FTL travel is possible, it’s slightly above zero. If you can travel faster than 10^9 c, that’s when distances stop being a huge problem. Before that though, distance ruins my dreams.

        I mean, thousands of humans do travel 14+ hours specifically for sex tourism.

    Yes I believe it is likely that non earth originated life exists somewhere.

    I absolutely do not believe “aliens” have visited earth in any way. I don’t even believe that “alien” originated radio waves have intersected earth, the odds would be crazy.

    Depends what you class as “alien”.

    Given that there are literally billions of galaxies out there and each one contains billions of stars with each one having the possibility of its own multi planetary system, it would be rather silly to assume that on our random planet of literally trillions of others, it’s the only one that life has or will evolve on. It might be not be life that has the ability to read a post on a smartphone but it might be more simple. It might be more advanced but I’m sure there’s probably some form of life.

    Whether any have been able to build inter-planetary/or inter-galactic vessels and travelled to Earth…highly unlikely. And we shouldn’t be so conceited that if they did come that they would come for us! We’ve only been around for a million years. We’re relative newcomers on the block.

    Life on other planets? Seems likely.

    Life on earth started pretty soon once the conditions were met.

    Intelligent life (humanlike), maybe not. Most probably not. Out of millions of species through billions of years only humans have evolved to have this kind of thinking machine during a relatively short period of time.

      The universe isn’t really that old so it probably just hasn’t had time to start getting crowded yet. We should really get our shit together in the next million years or so and get on top of that.

          Honestly given that we are a very intelligent generalist, I think it would be very hard to completely eradicate humans.

          But I would agree that we could have a crazy bad collapse and have to start way over due to a much smaller habitable part of the planet and maybe that habitable area shifts around making us nomadic or something. That would probably make it a lot harder to redevelop tech. Source: https://www.open.edu/openlearn/nature-environment/environment-understanding-atmospheric-and-ocean-flows/content-section-4

          Figure 18 shows that such a warm, stable period has been very unusual in the last 800 000 years, yet it is only during the Holocene that agriculture and the civilisations that rely on it have developed

          By “we” I’m really thinking of all earth based life/intelligence, rather than just humans as they exist today. But yeah if humans self-delete in a way that doesn’t involve being replaced by something similarly capable (for instance a planet of the apes type scenario), then it’s probably going to be a lot longer than a million years before we recover, which could start to erode our cosmic timescale head start over life elsewhere in the universe. So we really shouldn’t do that just yet.

    I think it’s likely aliens exist, but unlikely any alien species will be what we expect. I highly doubt we will see humanoid “little green men” or anything like the majority of science fiction portrays. Each planet is vastly different in just our solar system. The vast differences in environments across the galaxy will yield vastly different paths of evolution. We are only looking for “life” that fits our narrow definition based on Earth’s species - we have likely already missed signs of alien life.

            So what you’re saying is, it’s fine to get some floating balloon labs in the upper atmosphere that send down little spoons and drillbits for samples and cores, then?
