So, what does the Church of Jesus Christ of Latter Day Saints, have to say about creation and the age of the Earth (in reference to the YEC position)?

""The Creation
The six basic questions often asked about the Creation are when, how, where, what, why, and who. The first three of these—when, how, and where—are left obscure by the Lord in all the accounts we have of the Creation. He gave us only this point of reference concerning when the Creation took place: "in the beginning" (Gen. 1:1). We look with genuine interest at the work of persons who attempt to determine the age of the earth, but the answer may escape us all until the Savior reveals all things concerning this earth after the Second Coming In describing how the Creation was accomplished, he told us that he spoke and it was done As to where the Creation took place, we only have statements by early leaders that it was in the presence of God.""
