According to Mormonism, Jesus Christ created the heavens and the earth under the direction of Heavenly Father. He did not create the world from nothing, but organized eternal matter. Mormonism teaches that others were involved in the creation (Moses, Abraham, James, John, Peter, and Joseph Smith in their preexistent forms, among others).
