In Genesis 2, God decides to take a break from all the world-building and stuff he's been doing, so he creates a dude named Adam. Adam's got nothing to do and no one to talk to, so God creates a woman named Eve and tells them to start doing the nasty. They live in a perfect garden with no worries, but God also tells them not to eat from this one tree, or else they'll die. So of course, Eve eats the fruit and passes it to Adam, and God gets mad and banishes them from the Garden of Eden. Moral of the story: don't mess with God.
