its also hilarious that people are thinking we just happened to get our depictions of aliens correct. media portrayed them as little gray humanoids, and wow look they are little gray humanoids! in reality we don't even know the slightest thing about what extraterrestrial life might look like, there's no reason they HAVE to be humanoids (which is already an anatomical configuration that's optimized for earth) or gray.
I think it depends on thousands of factors about what aliens might look like. Environmental conditions, their equivalent of evolution, home location, species. I think they will simultaneously look exotic and familiar.
of course there will be shared traits among life (assuming extraterrestrial life would also be carbon based), but yeah it depends and at this point is just speculation with no basis unfortunately.
I'm a fan of the idea that certain alien species could be based on non-carbon elements or compounds. I think a silicon-based lifeform or a mechanical-lifeform that naturally evolved would be hella cool.
I very much doubt that a mechanical lifeform can evolve naturally.
I can understand doubt, but there is no real obstacle preventing it. Only needs to happen once for it to be true.
