Tolkien cast his mythology in this form because he wanted it to be remote and strange, and yet at the same time not to be a lie. He wanted the mythological and legendary stories to express his own moral view of the universe; and as a Christian he could not place this view in a cosmos without the God that he worshipped. At the same time, to set his stories ‘realistically’ in the known world, where religious beliefs were explicitly Christian, would deprive them of imaginative colour. So while God is present in Tolkien’s universe, He remains unseen.
