It doesn't even matter if Adam and Eve are literal or not. The point is that on that day they partook of the knowledge of evil. Up until then they had only known good.Now they know both good and evil. It is the point at which evil entered into the world.
A.S. I thought it a bit funny that you think I don't take the scripture literally. I actually do take it literally. I just don't get hung up on single points of scripture. I would much rather let all the scripture lead to a broader message.
