Maybe he's a fusion of our viewpoints. Perhaps Eru put part of himself into the world at the instant of its making. He didn't seem to concern himself with the actual "running" of the land, the Valar mostly doing that for him, but [erhaps he wanted a presence there. Not the whole of his form but enough of it to be useful.
