I have often thought about this exact scenario. One thing that I find, wrong with it, and there are many, is that really Adam, and especially Eve, were almost like children. They really had NO life experience. They were NOT even parents at this stage of the game.
If Adam was created as a perfect MAN, then he never had time to grow, and learn from childhood up. If you think about it, just because he was physically a "man", he would have been mentally an "infant" when first created. Logically the same would apply for Eve as well.
They were children, and the Genesis story heavily implies that the eating of the fruit occurred pretty early in the narrative. This again, gives tons of credence to the fact that both Adam and Eve were mere CHILDREN.
Who, and or what, was ALL these children knew? Well it was GOD himself. God was Daddy. God was Mommy. God raised them from creation, and taught them EVERYTHING.
Well, evidently, it seems as though he did a poor job. The FIRST time, a trial was put before them, they failed miserably. Can you imagine the first time your young child makes a serious mistake, you kicked them out of the house, and cursed them.
Adam and Eve, according to the Genesis narrative, were simply children, who were DECEIVED, and had NO knowledge of anything other than their creator. Sounds like a VERY harsh punishment for 2 innocent children, who were deceived by a being that was perhaps BILLIONS of years older than them, and of not only a higher intelligence, but was actually a HIGHER LIFEFORM.
The sicker thing about it, is that WE are paying the price, and WE were NOT even born perfect, and our lives are supposedly still being "deceived" by these billion year old, higher lifeforms, called angels/demons. DAMN, what chance do ANY have against this ?????
