No offense taken DC. I see the Genesis story as allegorical - the garden and the snake - it's a way of telling us something in terms we can understand. But I do believe that this story has been handed down to us from God as a means of us being able to understand HIM. We see things with more complexity now, so the story seems like a fairy tale. But the moral that is derived from the story is the truth.
Not to further digress, but I always interpreted that particular anecdote as a euphemism for them having sex.
I mean, for one, the deceiver is described as a serpent holding an apple (a phallic symbol), which Eve is seduced into consuming. One of the punishments against Eve is that she will experience painful childbirth, the obvious end result of sex.
Because writing systems didn't show up in humanity until about 5,000 years ago at the earliest, there could not have been any eyewitness accounts to the story, meaning that most of Genesis had to come from dreams and visions, which are in need of interpretation, just as prophecies have routinely been interpreted.
