Could it be possible for us to understand God as the Creator of the multiverse instead of a single man-centered universe?

It may be possible for us to compared those 3 created worlds (Heaven, Hell and Earth) as a version of the Multiverse. See my theory in that paper. I accept any comment you have to argue pros or cons.
