 Because Mormonism teaches that Jesus created the universe, yet his father, God the Father, once dwelt upon an earth as a mortal, it may be interpreted that Mormonism teaches the existence of a multiverse, and it is not clear if the other inhabited worlds mentioned in LDS scripture and teachings refers to planets within this universe or not.The idea of multiple universes has been entertained by Mormon leaders since its beginnings.Brigham Young taught there is no such thing as "empty space", lending to the idea that any space beyond this universe is occupied.
