The Garden of Eden is the story of human conception with the expulsion from the Garden being the story of human birth into the world of moral conflict and dualities. We are the characters (right here and now) portrayed in the Genesis story.
That is certainly one way to approach the Genesis story. I take a Jewish approach, there's no one way to view Scripture. I actually like Buggsy's view, but not to the exclusion of other views, including the traditional and literal view.
