Note above how a Mormon condemns the Biblical view that God is Omnipresent. That's because Mormons have a puny physical god that spends all day procreating babies, and has to ***ign duties to his underlings. He didn't even create anything, just ***igned some of his kids to reorganize matter. This god is a total fiction.
