For us, it's just another 5 years old.
There is no similar chain of logical deduction based on empirically observed facts that can lead you to the existence of gods or ghosts or demons.
Aliens are not like 'gods', they are like black holes after we realized they probably exist but before we found physical evidence for them.
A process strikingly similar to what religious people do with gods, angels, etc. There's also no real data on where the universe comes from, so they can imagine that it is due to god(s). God used to be on a high mountain, or just above the sky. But like the Martians, He has had to up sticks and move to loftier realms.
I'll also note that some of the alien-imaginers use exactly your reasoning to derive gods. Statistically, aliens must exist, and they must have existed long before us, and they must therefore be so technologically advanced that UFOs are real and we can't prove it just because they are so superior. Or, alternatively, that those aliens caused us in one way or another, from shaping our evolution to seeding our planet to creating the universe.
You can doubt the existence of intelligent aliens. But they obviously aren’t in the same category as religious beliefs. On the other hand, assuming we are somehow special and must be the only intelligent life is quite in line with religious thinking.
We do have data on life in the universe: earth. Very few natural phenomena occur a single time and never again. Apart from early universe events like the big bang and expansion, I can’t think of an example.
Nah. All of those were things that there were specific reason to believe based on theory and evidence. But it can be a fine line. Look at how quickly quantum mechanics went from abstruse high theory to being used to support absolute woo. [1] Or look at how black holes went from interesting mathematical concept to magic plot device. [2]
Do I grant the theoretical possibility of intelligent life somewhere? Sure, and I never said otherwise. Do I believe it's a lock? Not at all. If we somehow survey the universe and discover we are alone, then our theories will adjust just fine. There is no evidence to the contrary to be overcome.
So yes, in terms of an explanatory device for phenomena observed on earth, aliens and gods are in exactly the same category of "unevidenced anthropomorphic agents that people have been inappropriately using as explanations for millennia". Because people are like that.

Sorry, you’re just wrong. The possibility of intelligent aliens is on firm scientific ground, which is why we have projects like SETI running. Aliens aren’t like gods or angels, regardless of how many times you repeat it. Certain people might treat them that way, just like people abuse all kinds of scientific concepts. That doesn’t merit a categorical dismissal.
I never said the possibility of aliens somewhere in the universe and somewhere in time was scientifically impossible. Indeed, I've said the opposite, something you seem dedicated to missing if you're still acting otherwise.
I am specifically saying that there's no scientific justification for using aliens as an explanatory device for things that are happening right here on earth. That's just fantasy.
I obviously don't think quantum mechanics is like religion when it's in the hands of Paul Dirac. But I do think it's effectively religion in the hands of Deepak Chopra. Similarly, I don't think the SETI folks are religious kooks, but I do think UFO cultists are.
We know intelligent aliens might exist. We know that if they did visit earth, it would mean that they have technology that far exceeds our own. We have extensive documentation of events that, naively, look like some kind of extremely advanced technology that is far beyond human capabilities. So far, we have found no natural explanation, no explanation involving instrument malfunction, and no explanation involving human actors. That doesn’t mean it’s aliens, but it does mean it could be. If you think they should be crossed off the list, you’ll have to do better than making assertions.
But my point is that there is exactly the same level of evidence for gods and aliens being behind these. I'm not saying either one's inconceivable. I'm just saying that I'm going to treat them both with the same level of seriousness. That is, approximately none.
I'm going to treat unexplained, poorly documented phenomena as unexplained, poorly documented phenomena. Does that mean I'm missing out on the Virgin Mary or aliens or ghosts or whatever? Possibly. But as a practical matter, a century's worth of paranormal hoohah shows I could waste my entire life on this stuff and never get anywhere. I am content that there are enough devoted skeptics out there that if any of the paranormal brigade comes up with some clear and repeatable evidence, I'll hear about it. Until then it goes in the bucket with dowsing and spirit guides and whatnot.
You can rule it out because we've never found evidence of gods existing in the universe, and there's never been a scientific theory put forward for how they could exist that is consistent with our understanding of biology, astronomy, and physics. This obviously doesn't apply to intelligent life, but something tells me you aren't going to concede that. Thanks for the discussion.
Indeed, the god-believers have a lot more "evidence" than the alien-believers do, even if I think it's all pretty specious. And I'll note that the god-believers don't have to prove consistency with biology, etc, in that in their view, that's god-created. Plus, there are things that the god hypothesis explains that the alien hypothesis doesn't, like why we have universe at all.
Again, I think it's all claptrap. I get that you're mad that I see them as the same. Most religious people would be insulted in the opposite direction. But from my perspective, religious people are like that. So yes, you're very welcome for the discussion, and I hope you find it helpful down the road.
This seems like fairly closed thinking. We’ve observed strange behavior at the quantum level. We have plausible theories of wormholes and multiverses. It’s conceivable that some civilization has assembled FTL travel from these and other natural phenomena yet unknown.
> it's economically unreasonable to think some species is going to invest in generation ships
We’re working on AI and we can sequence DNA. A sufficiently advanced civilization could send a ship that can synthesize its crew upon arrival.
We have observed quantum entanglement. Perhaps information can travel faster than light and all you need to send physically is the equivalent of a quantum modem attached to a Star Trek replicator.
I too consume a lot of science fiction, but it's important to remember that it's just writers making shit up. Perhaps FTL is possible. Perhaps angel are real. Both are things people want to believe in, and both have facially plausible literary explanations, but they have equally good scientific evidence at the moment.
Take gods. Even most theists don't believe in most gods. An atheist, as the saying goes, is just a person who disbelieves in one more god than average.
In theory, everybody has to admit that all gods are possible. Does Zeus exist? No idea. Does Bast exist? No idea. Does Yahweh exist? No idea. It's not like we can prove that they aren't out there somewhere.
But what we do know is that a lot humans have made up a lot of gods. We know that people make up and believe in all sorts of things with no evidence at all. So if something fits the same pattern, then we actually have reasonable evidence that it's just another one of those things.
So in a world of people who will take "no idea" as permission to rant more about their theory of chemtrails or ZOG or how the true Messiah lives in a heavily fortified compound outside of Waco, TX, I think an honest and accurate "no idea" isn't enough. Would that it were.
However, I doubt you're going to spend much time on that, and I'm not going to spend much time on other things that are merely conceivable.
The existence of aliens, sure. But the presence of aliens on Earth pretty much does. There's no reason to think FTL travel is possible, and it's economically unreasonable to think some species is going to invest in interstellar generation ships to cross the great interstellar gulfs just so that they can fuck around with pilots and anally probe hayseeds.
