Im sure you will agree that the jews copied the origin stories in Genesis from other cultures. The reason for the extraordinary lifetimes for the early characters it the jewish copier misunderstood the source text and took some word to mean years when it meant months or other unit of time. From that the numbers are nonsense. Im not sure how this addresses the other problems wiht the text like nonsense ages for father and mothering, but it does seem more logical. Then again the ancients also loved to give their gods extraordinary lifetimes. Many cultures even said their gods were immortal and the further back in time you go the boundary of man and god gets blurred.
