"The evidence seems to me to point toward an age of the earth between 4 or 5 billion years and to the existence of pre-Adamic man. I don't think that it is reasonable to explain the observed geologic formations on the theory that they were moved from some other worlds. I have no difficulty reconciling myself to the idea of life before Adam and to a great age of the earth. Our scriptural accounts are brief and don't seem to me to rule out these possibilities. The scriptural emphasis is on God's dealings with Adam and his descendants and the treatment of pre-Adamic history is sketchy, no doubt for a good reason. It seems, to me, clear that the Lord used the Prophet Joseph to restore His gospel. This is the important thing to me. Just how he runs the world, I'm obliged to leave up to Him. All I can do is find out how he does it by every means available."
