"Latter-day Saints have, in addition to the biblical Genesis, two modern restorations of ancient scriptural accounts of the Creation in the Book of Moses and the book of Abraham. Related authoritative information also appears in the Book of Mormon, the Doctrine and Covenants, and the LDS temple ceremony. Drawing on this wealth of creation literature, Latter-day Saints understand that Jesus Christ, acting under the direction of God the Father, created this and other worlds to make possible the immortality and eternal life of human beings who already existed as spirit children of the Father. This understanding differs from both scientific and traditional Christian accounts in that it affirms God's purpose and role, while recognizing creation as organization of preexisting materials, and not as an ex nihilo event (creation from nothing). . . . A significant feature of this revealed account is that both the space and the materials for the earth explicitly existed before its creation."
