Neal A. Maxwell: God’s revelations do not usually give us answers to the how and when questions, such as details concerning the creation of the earth. Yes, there are revelations such as on the building of Noah’s ark—a revelation not reusable, by the way—and on other tactical matters, but the recurring themes of the revelations are spiritual.
Thus the Creator of the universe does not choose to dazzle His audiences with data concerning the Creation. Rather, as a Perfect and Loving Shepherd, He is interested in the central needs and concerns of His sheep in His many folds.
