ETs simply make no sense with God’s plan of salvation.
Adam’s sin cursed ALL OF CREATION.
Not really fair for that ET out there, now is it, unless they sinned against God as well?
And then did Jesus have to go and die “once for all” on each of these other planets? (see the graphic above showing an alien “Jesus” dying on crosses on each planet)
Not in the scope of the Bible, for sure. But the Bible doesn't bring us all of the stories of the Universe, it ONLY brings us the story of this one single planet.
There certainly could be similar dramas played out on billions of worlds, couldn't there? Each of those worlds could have its own Bible, couldn't they?
The Bible does not address the question of ET life, one way or the other. It wasn't necessary for it to do so.
You would have an argument ONLY if the Christ story occured after we developed interstellar travel, and became really fruitful and multiplicative.
Why not? He is a pretty tough rascal.
Perhaps God brought salvation to them in other ways. Perhaps they did not fall in the first place.
The Bible brings US our salvation. We're really too small to be concerned about the really big picture ... that big picture is sized about right for God.
