There’s no inconsistency between the Bible and the possibility of alien life. Actually Ezekiel’s wheel argues aliens are in the Bible. (No, I’m not espousing that, just bringing it up.) It wouldn’t be relevant in umpty-ump BC for God to spake; “Oh, and I’m doing the same thing on other planets in other solar systems. Eh...planets...this thing you’re standing on is a planet. Yes, I know I called it Earth a few chapters back, but it’s a planet and it goes around the sun. Uhm...no, actually, the Earth goes around the sun...no, you won’t fall off on the other side because the Earth is round...Uhm...because the Earth is so big you’re stuck to it by something called ‘gravity.’”
I can imagine why God wouldn’t want to get dragged into THAT conversation. Maybe God was thinking, the Bible is allegorical and it’s intended to teach them the basic fundamentals of civilization and they’ll figure everything else out later.
Yes, there is: as this author stated: the creation was meant for man, beside if Christ died to redeem us (and creation is fallen) then He would have to die thousands of times, on 1000’s of worlds (clearly the Bible says He only died once!).
So yes, alien life is incompatable with Christ (other than simple celled critters/bacteria).
