<human>:  Why did the author use the word ‘fall’ in the title of the book ‘The Fall of Man’?
<bot>: The author was referring to the fall of Adam and Eve from the Garden of Eden. In Genesis 3:22, God tells Adam and Eve that they are no longer to eat from the Tree of Knowledge of Good and Evil, and that they must not eat from the Tree of Life. The Tree of Knowledge of Good and Evil was a beautiful tree in the Garden of Eden, and the Tree of Life was a tree that gave Adam and Eve immortality. Adam and Eve disobeyed God, and God punished them by making them mortal.
