If the Tree of Knowledge of Good and Evil is "Satan", and the Serpent spoke to the woman saying in so many words, "Hey, didn't God say you can eat from ALL the trees of the garden", then aren't the Serpent and the Tree of Knowledge two separate beings? It wasn't the Tree of Knowledge that spoke to the woman, it was the Serpent pointing to that Tree and deceiving the woman into partaking of it. The Serpent was a controlled agent of Satan who deceived the woman into the unholy union with him. Isn't this a more accurate account?
