Christianity IS Geocentrism.

[Confused Ape]

You mentioned that Christianity is not geocentric, because it's based around Christ and his teachings, not us. I gotta point out that Jesus came to save humanity from sin. Humanity is a noun exclusive to this planet, and actually, if there is other life in the universe created by God, then the term earthlings might be more apt. And most importantly, if God created other life on other planets, they would not be Christians. Unless Jesus was also born, lived, was crucified, and resurrected all over again throughout the cosmos, then Christianity applies strictly to Earth, and especially because of it's sluggish pace at accepting the grander scale of the universe, I consider it a geocentric philosophy.

That reminds me of Perelandra by C.S. Lewis.

The Adam and Eve of Perelandra are humanoids who live on floating rafts of vegetation and there is only one mountain which is fixed land. They have been forbidden by a being who represents Jesus in the story to spend a night there. Weston, the villain, has been possessed by a demonic entity who tries to tempt the woman into disobeying. The hero, Ransom, defeats him so the fall isn't repeated. This means that the descendants of Perelandra's Adam and Eve won't be in need of redemption.

If God created other beings in the universe in his own image, would they need to be redeemed by Jesus if their equivalents of Adam and Eve didn't disobey? They'll still be living in their planets' versions of Eden.
