Mormons believe that Elohim and his Kolobian polygamous wives have been playing celestial hide-the-pickle for eternity with their exalted, resurrected bodies. This is the ultimate goal for all Mormons. To become like Elohim and create their own planets and make infinite ghost children with their own celestial harem, Elohim's wraith offspring need a physical body. I know it doesn't make any sense why a physical body is needed to make a ghost baby, but God's ways are not our ways. Or something.
