Of all the trees in the Garden of Eden, Adam and Eve chose to eat fruit from the one they were not supposed to eat from. According to the Book of Genesis, God told Adam not to eat from the Tree of Knowledge. When Eve was created, a wily snake convinced her that eating a fruit from that tree would give her wisdom. As is still true today, people want what they can't have. She and Adam partook of the forbidden fruit and were swiftly kicked out of the garden and denied immortality from another tree in the garden: the tree of life.
