The Adam–God doctrine (or Adam–God theory) was the most prominent of several theological ideas taught within mid-19th century Mormonism, and is part of the modern theology of Mormon fundamentalism. Introduced by Brigham Young in the 1850s, the doctrine teaches that Adam is both the common ancestor and the father of spirits for all people who are born on this earth. According to the doctrine, Adam was once a mortal man who became resurrected and exalted. From another planet, Adam brought Eve, one of his wives, with him to the earth, where they became mortal by eating the fruit of the Garden of Eden. After bearing mortal children and establishing the human race, they returned to their heavenly thrones where Adam serves as the god of this world. Later, as Young is generally understood to have taught, Adam returned to the earth to become the literal father of Jesus.
