Life Before, pg. 39; “In 1833 the Lord revealed to the Prophet Joseph Smith that “man was also in the beginning with God. Intelligence, or the light of truth, was not created or made, neither indeed can be.” (D&C 93:29.).” – Brent Top
Psalm 8:3-5; “When I consider thy heavens, the work of thy fingers, the moon and the stars, which thou hast ordained; 4 What is man, that thou art mindful of him? and the son of man, that thou visitest him? 5 For thou hast made him a little lower than the angels, and hast crowned him with glory and honour.”
I cannot imagine the Lord would tell Joseph that He was unable to create mankind or that He didn’t have the power to create the earth out of nothing.
