I agree with you.Lewis's space trilogy is great... especially Perelandra.
I disagree with the logic of saying there can't be intelligent life elsewhere in the universe because Jesus would have to die for them too. It assumes two things:
Neither of these are necessarily true. Angels, for example, are intelligent lifeforms. Two thirds of them didn't sin, and therefore didn't need to be redeemed. And the third that did sin did not obligate Jesus to die for them. Salvation is purely by grace.
- The other lifeforms are also fallen.
- If they are fallen, Jesus is obligated to save them.
I think it possible that there could be life on other planets, but not because the universe has a huge number of stars (and presumably planets). God can do what He wants. He may have populated the universe with other forms of life, or He may not. Whichever it is is not important for us to know, otherwise God would have told us.
What do you think of my theory that the "alien phenomena" is the activity of demonic manifestations? Do you think it is possible?
