Recently there has been a lot of fiction published purporting to be the truth. Parts of the Bible are historical fact that can be proven, but much of it is a work of fiction written by both known and unknown authors; take the story of Adam and Eve for example. If you take it as fact, it is so full of holes even a six year old child can see through it.
As I see it the author of this particular story whoever he or she might be, was not recording fact but creating a story that is full of symbolism. Take when Adam and Eve ate the fruit from the tree of knowledge for example. Now there’s a clue right there.
It was not a Granny Smith apple tree it was a ‘Tree of Knowledge.’ Symbolic of how when human kind’s brain developed he gained knowledge that could be used for both good and evil. In other words human kind learned to sin. As a symbolic story I find its message far more powerful than taking it as fact or history.
