Also, I don't know how you can say with authority that it is allegory. You can think that is probable, but how do you say certain with authority? I'm also interested in what other absurd leaps you think would be connected. I'm not trying to be sarcastic. Just curious, since I'm not seeing what you're seeing :)
I'm going to start a research project soon on the Genesis Adam and Eve account.
In response to your question about my conviction of the account's original intention: I ask you a question:
If all or some of the Adam and Eve creation account is literal, what parts should be taken literal and why?
^ Answer this question only using the Genesis account itself.
Information from other Bible books can not rightly be used as evidence since they were written long after (and a variety of other reasons). These other future references to the story can be investigated and their purposes for the reference to Adam and Eve can deduced.
I am refering to the inception of the story. Why must the author's intentions for writing remain so ambiguous! We sometimes take for granted that Genesis was placed at the beginning of the Holy Handbook many years after it was written. Many seem to overlook this huge fact for some reason. I for one feel it is imperitive for one to understand the story at all.
It's application today is extremely clunky and frankly lazy. The story is rich with symbolism and covers many deep themes. The story also gives real insight to who our ancestors were: they were a smart deep thinking folk. They came up with a brilliant piece with the Adam and Eve story. The reason I know it's allegory is because it's so specific. Take a few parts of the symbolic pie:
Cunning serpent that seduces it's subjects with power and understanding
Forbidden Fruit with real mystical effects upon eating
Tree of Life
Man formed FROM the Earth
Women formed FROM Man
God "breathing" into Man
^ Did these events actually transpire? No, it is absurd to believe that these are the actual events transpiring from natural cause and effect. These are SYMBOLS and only symbols. As real events, in part or in their entirity, the topics they were concocted to represent fall by the wayside.
