If we're capable of reaching them, it's possible that their homeland could support human life, thus also allowing human beings to escape the events of Revelation. That's probably not going to happen.
If their area cannot support human life, it may be possible for them to exist, but that would just be a random animal on another planet, basically on par with the bacteria on Mars. Hardly E.T.
I do think Elon might get away with his Mars project, but it would require the humans involved to be supplied by Earth or die out there. When the antichrist takes over, they will have to return to Earth or die. Same with the International Space Station.
