Why would u read the buy-bull?

A fun thought I had as a christian is that the Biblical story of creation describes the renewing of the world after the cataclysm that ended the Fourth Age. Eru was trying to partially undo the Marring of Arda, so He stepped in Himself to resurface the lands back after the desctruction of the world. He first made the world flat again to make it closer to the original vision of the world (although he later made it round again after the Biblical flood, just like with the flood at the end of the Second Age). Then He remade light again, as He got rid of it during the cataclysm, hence "Let there be light". Then He made a new sky for the new flat earth. Then He resurfaced the world and remade plants without Morgoth's marring. Then He put light back into the Sun and Moon and placed stars back into their place on the sky. Finally He recreated all the animals unmarred. After all of this He created 143 new people to repopulate the Earth along with Adam (from Sindarin Adan, "man") who was descended from Aragorn. He gave them life longer than even those of the Numenoreans.

I would have already created a new church if I was protestant, but we catholics don't really do that so I'll just talk about it here. And I know there is a ton of plotholes, but you could somehow make it work I guess.

Would not really work as humanity is already fallen in Tolkien's work and the Old Hope - promise of Eru entering Arda - is already given in-story according to the "Athrabeth Finrod ah Andreth". So makes no sense to redo it again all over.
