History of the Earth

Elder Jeffrey R. Holland, Where Justice, Love, and Mercy Meet, April 2015 General Conference
"In our increasingly secular society, it is as uncommon as it is unfashionable to speak of Adam and Eve or the Garden of Eden or of a “fortunate fall” into mortality. Nevertheless, the simple truth is that we cannot fully comprehend the Atonement and Resurrection of Christ and we will not adequately appreciate the unique purpose of His birth or His death—in other words, there is no way to truly celebrate Christmas or Easter—without understanding that there was an actual Adam and Eve who fell from an actual Eden, with all the consequences that fall carried with it.

"I do not know the details of what happened on this planet before that, but I do know these two were created under the divine hand of God, that for a time they lived alone in a paradisiacal setting where there was neither human death nor future family, and that through a sequence of choices they transgressed a commandment of God which required that they leave their garden setting but which allowed them to have children before facing physical death.3"
