Orson F. Whitney teaches that the Church promises faithful men and women will become "Adams" and Eves" to future worlds.
Orson F. Whitney, "Divine Evidences of Truthfulness," in Brian Stuy, ed., Collected Discourses, 5 vols. (Sandy: B. H. S. Publishing, 1987), 4:336-37
It teaches that the worlds on high, the stars that glitter in the blue vault of heaven, are kingdoms of God, that they were once earths like this, that they have been redeemed and glorified by the same laws, the same principles, that are applied to this planet, and by which it will ascent to a perfected and glorified state. It teaches that these worlds are peopled with human beings, God’s sons and daughters, and that every husband and father may become an Adam, and every wife and mother an Eve, to some future planet.
