Frozen Discovery

Q: A man is taking a hike in Alaska. He is walking along the ice, when suddenly, he slips and falls. Upon getting to his feat, he realizes that there was something stuck in the ice below where he fell. He wiped off the snow, and dug them out with his ice picks. He quickly discovered that the objects were two frozen human beings. As soon as he inspected the bodies, he knew right away that they were Adam and Eve. How did he know?

A: They had no belly-buttons! According to the bible, Adam and Eve were not born, therefor they would not need an ombilical cord, therefor they woould have no belly-button!
