Mormon cosmology teaches that the Earth is not unique, but that it is one of many
inhabited planets, and each planet created for the purpose of bringing about the "immortality and eternal life" (i.e., the exaltation) of humanity. These worlds were, according to doctrine, created by Jehovah, the pre-mortal Jesus. Because Mormonism holds 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 Mormon scripture and teachings refers to planets within this universe or not. Mormon leaders and theologians have taught that these inhabitants are similar or identical to humans, The doctrine of other worlds is found in Mormon scripture, in the endowment ceremony, and in the teachings of Joseph Smith. In addition, many LDS Church leaders and theologians have elaborated on these principles through
exegesis or speculation, and many of these ideas are widely accepted among Mormons. The LDS Church teaches that after death and resurrection, that exalted adherents will continue having marital sexual relations, create worlds, and have spirit children over which they will govern as gods.
Official sources According to a revelation dictated by Joseph Smith, Jesus is the creator of many worlds, so "that by him, and through him, and of him, the worlds are and were created, and the inhabitants thereof are begotten sons and daughters unto God." Another part of Smith's translation portrays the biblical character
Enoch as stating that if there were "millions of earths like this [earth], it would not be a beginning to the number of [God's] creations; and [his] curtains are stretched out still." Finally, the portion of the LDS Church's endowment ceremony depicting the creation of the world refers repeatedly to "worlds heretofore created". In the portrayal of the
Garden of Eden story during the endowment, after
Lucifer has tempted
Eve to eat of the fruit of the
Tree of Knowledge, God the Father asks Lucifer what he is doing, and Lucifer replies "that which has been done on other worlds."
Noncanonical statements by church leaders Statements of early church leaders According to Latter-day Saint Oliver B. Huntington, Joseph Smith said there was life on the
Moon; Huntington also reported that he was promised in a
patriarchal blessing given to him by
Joseph Smith Sr. that he would preach the gospel to inhabitants of the Moon. LDS researchers John A. Tvedtnes and Van Hale have expressed doubt about the reliability of Huntington's claims. Regarding the first, it is likely that Huntington was repeating a description provided by another Latter-day Saint, Philo Dibble. Regarding Huntington's second claim, the official LDS Church's record of the blessing indicates that it was given to Huntington by his father, William Huntington, not by Joseph Smith Sr. There are no contemporary reports, records, or any other written support of Smith's alleged views or statements on extraterrestrials, nor are there any reports of statements other than the one claimed by Huntington, which is unverified and therefore possibly unreliable. Tvedtnes and
James B. Allen have pointed out that, unlike many of Smith's statements, there is no indication that Smith claimed that any such alleged opinions on extraterrestrials was
revealed to him by God nor that Smith was speaking under any prophetic authority. In a statement given on July 24, 1870,
LDS Church president Brigham Young discussed the possibility that the Sun and the Moon were inhabited, but said these were his own personal thoughts. In response to a claim of his being ignorant on the matter, Young agreed, asking, "Are not [we] all ignorant [about these matters]?" In any event, Young's personal beliefs on the subject of "inhabited worlds" are not considered LDS Church doctrine.
Modern leaders Some modern LDS Church leaders have taught that people live on other earths. For instance,
apostle Joseph Fielding Smith (1876–1972) wrote:
Spencer W. Kimball wrote that God has created many worlds populated with his children, and stated, "Are planets out in space inhabited by intelligent creatures? Without doubt." Apostle
Neal A. Maxwell (1926–2004) wrote, "We do not know how many inhabited worlds there are, or where they are. But certainly we are not alone." ==Mormon metaphysics==
