It seems that a lot of traditional religion that seems absurd or irrational, such as an afterlife, ressurrection, a different world of existence, etc., actually becomes possible if some different scientific theories turn out to be true. For example, if more than 4 dimensions really do exist, then I suppose it's possible for some type of reality to exist there. If we exist inside a computer simulation, I suppose it's possible for the game to be turned off and turned on again, restarting the same characters. If there is a parallel universe, then I suppose exact copies of us could exist there. And so on.
