Paragraph 15
"Actually the Bible is so old that it has three documents written before the flood of Noah’s day four thousand years ago. The first document contains God’s dictation to Adam of the basic facts about earth’s creation. The second document, called the “book of Adam's history” (Gen. 5:1), was written by Adam himself and was carried in the Ark through the flood by faithful Noah and eventually given to Moses, who incorporated the document as part of the book of Genesis in the Bible"
