It’s more important that certain people get to retain their simplistic view of the Bible than that trillions of sentient beings have a chance for eternal life.
That’s exactly why there are no “aliens”. Jesus would have to go to every planet in the universe and be crucified again.
The Bible says Christ died only once for all.
Also, God does not send anyone to Hell. Those that go there choose to go there.
It could be the eternal post earth life is on the distant planet
The aliens are us
