I keep coming back to this one....
From Wikipedia, the free encyclopedia
Adam and Eve, according to the creation myth of Abrahamic religions,[1] were the first man and woman. The story of Adam and Eve is central to the belief that God created human beings to live in a Paradise on earth, although they fell away from that state and formed the present world full of suffering and injustice. It provides the basis for the belief that humanity is in essence a single family, with everyone descended from a single pair of original ancestors
OK everybody in the world is from Adam and Eve. From the IBM National geographic study they can trace Adam back to one guy in Africa and everyone has his DNA. Ok, cool. But..... this guy wasn't the first guy, only the first to survive and Eves line goes back many more years. How can this be?
