Alien civilizations? No. No evidence to support this. But alien life form like bacteria and other organisms? Possible, but still, evidence is scant. It’s difficult for some to accept that we are alone but the lack of evidence suggests a very strong possibility that there’s nothing out there.
We have explored an infinitesimally small portion of our galaxy, let alone the universe. We have barely even explored our the planets in our own solar system. What you’re saying is the same as looking in a drop of water and saying that fish don’t exist in the ocean. We have no real reason to believe that life ONLY exists here on one planet of the estimated 100 billion planets in our galaxy. Which is one of 200 billion galaxies.
The lack of evidence thus far only suggests that life might be more rare, or harder to detect, than previously thought. It implies nothing about us being truly alone in the universe.
Do I think think that alien intelligent life exists? Yes, the universe in unimaginably huge, more than likely that we are not the only ones. Do I believe those that say they had encounters? lol, nope
We do not understand enough how life begun on Earth to have any meaningful idea of how probable it is for life to exists somewhere else. Maybe in the near future we’ll be able to conjecture, but not now.
I am fairly confident that alien life in some form exists somewhere in this universe. It may only be some colony of bacteria-like cells on some rock on the total opposite side of the universe that we’ll never be able to even detect let alone see with our own eyes, but I’m confident that something somewhere out there will meet some definition of life.
Moving up the scale, I get less and less confident. Simple multicellular life- still pretty likely. Complex plant/animal/fungus-like life- not very likely. Intelligent life that we can in some way make meaningful contact with- very extremely unlikely.
Not 100% proof. That would require the universe to be infinite, which it still might not be if the curvature is within the tiny margin of error. It’s close enough to proof that it might as well be the case. The entire universe couldn’t be less than something like 130x the size of the observable universe, though… unless it has nontrivial topology. There’s always a caveat.
Alien, extra terrestrial life? Odds are yes. Sentient extra terrestrial life? Odds are slimmer but I’m guessing we’re less unique than we are on this planet. Extra terrestrial life with the technology to visit this planet? I’m not so sure about that one. Extra terrestrial life with the technology to visit this planet that still wants to after seeing what we’ve done with it the last few years? Yeah no.
Didn’t NASA find fossilized microbes on Mars or a meteorite or something in the 90’s? Sure it wasn’t alive, but it kinda proves alien life existed in some form just in our own backyard.
With the sheer abundance of life forms just on our one planet, it would be fucking weird for their not to be alien life elsewhere in the universe.
What?.. no. That would be confirmed life on another planet. It would be the single biggest discovery in human history. You would have heard if that was the case. “Fossilized microbes” would be “life”. Nobody needs the life to still be alive to be a huge, huge deal.
If you’re thinking the word “organic” means “microbe”, it doesn’t. I guess this is the consequence of all the harm to the public understanding that all the shitty headlines caused trying to get clicks but still being “technically correct” despite knowing it will be misinterpreted as “life”.
Probably yes. The real question is why now are US senators asking the defense department about what craft they have?
The newish committee AARO is basically useless but there are whistle blower protections in place now for anyone who comes forward with information about crash retrieval programs etc.
David Grusch gave a multiple hour interview with Ross Coulthart last month as one of these whistleblowers. News Nation ran an edited hour of that interview. He makes some bold claims and nobody has really come forward to discredit him since. There are allegedly more whistleblowers to come.
I totally agree with you on that. Still out of all the other possible scenarios at our current stage of civilization you gotta admit a benevolent overlord is the best case scenario
Aliens very obviously exist. Life evolved on Earth. The idea that it has never done that elsewhere is ridiculous. The question is how spread out they are in both time and space. The fact that we see no clear evidence of them points to “very spread out”. But it could just be complex life, or intelligent life that is rare, which is why we look for much fainter signals that we’d only see when specifically looking, like with JWST. Either way, they exist. Whether that existence has any relevance to yours is up for debate.
No they don’t. And you genuinely do not understand the gulf that evidence would have to overcome for aliens to be more likely than literally any other explanation for any phenomena you’re talking about. Including explanations that require extremely unlikely coincidences. Because coincidences happen. But if aliens have visited Earth, that requires an unbelievable amount of observations about the universe to be explained. And truly, the evidence to overcome that would be MORE than a good video. And we don’t even fucking have that. It’s pathetic how people act about UFOs and aliens.
The fact that it’s always bad evidence, or indirect evidence, should tell you that it’s always the same bullshit. If you believe it, it’s because you want to, not because there’s the tiniest reason to.
Life evolved on Earth. The idea that it has never done that elsewhere is ridiculous.
I was going to question this, just because I think people often jump to conclusions based on the universe being very large, but as I did just a bit of research it does seem like nothing too unlikely happened to create Earth. You seem to need liquid water. Maybe that water is generated on the planet or maybe it’s delivered by impacts with icy meteorites or asteroids. We have yet to find another planet with liquid oceans, but it’s hard to imagine why it would be so unlikely for enough Earth-like planets to have sprung up to have a good chance of fostering life. The fact we haven’t found an ocean world would seem to speak more to the massive limitations of our knowledge of other planets. You need other things for life as well, but the same argument seems to follow, in that none of the requirements seem like they have a reason to be that rare. But as limited as our science is, and as limited as my understanding of the science is, I have to admit I really do not know what to think. I don’t think our statistical intuitions are useful when thinking about probabilities of planetary or astronomical phenomena.
Yes, it seems pretty untenable that rare earth is the explanation for the lack of evidence of any life outside of Earth. But even if it is true that we’re the only life in the observable universe, the universe is still much bigger, and in many physicists opinion, probably infinite.
The fact that life seems to have evolved on Earth as soon as it was possible to is some evidence that abiogenesis is not the bottleneck. But the usefulness of this observation depends on the distribution of other things we don’t know. For example, if on planets where life evolves later, life never makes it to human-level intelligence before the planet becomes uninhabitable, then our early abiogenesis is survivorship bias, rather than something we should expect to be in the center of the distribution of when abiogenesis happens on a planet where it is possible.
In my opinion, a definite yes. The only issue is that the Universe is so mind bogglingly huge that the statistical probability of finding one is very low.
