While i do think life exists elsewhere in the universe, I think the chances of extraterrestrial biological entities coming to our planet is exceedingly unlikely. Space is just too big, and there isn’t any hard evidence that faster-than-light travel is even possible.
Although, the universe isn’t just big – it’s old. There could be some ancient civilization from an ancient planet that became uninhabitable long ago. If they were technologically advanced enough to escape their solar system before things went tits-up AND were able to live multiple generations fully in space AND they just so happened to set out in our direction, I guess it’s possible that they found us. Even then, i would expect any UFOs or whatever would merely be probes, not the actual biological entities themselves.
wouldn’t it be awesome to get a case pushed up to the supreme court or something arguing that trump is ineligible to run for president because he “won” in 2016? it would just so perfectly highlight the hypocrisy of it all
