Under the direction of Heavenly Father, Jesus Christ created the heavens and the earth (see Mosiah 3:8; Moses 2:1). From scripture revealed through the Prophet Joseph Smith, we know that in the work of the Creation, the Lord organized elements that had already existed (see Abraham 3:24). He did not create the world "out of nothing," as some people believe.
The Creation is an integral part of Heavenly Father's plan of salvation. It gives each of us the opportunity to come to the earth, where we receive a physical body and exercise our agency. In the premortal Council of the Gods, the following declaration was made: "We will go down, for there is space there, and we will take of these materials, and we will make an earth whereon these may dwell; and we will prove them herewith, to see if they will do all things whatsoever the Lord their God shall command them" (Abraham 3:24-25).
