That does not compute. Do you mean to say the (supposedly benign) omnipresent, omniscient, omnipotent Creator was unable to prevent it ? The notion is incoherent. To argue that He decided to change the matters after a couple of dumb and easily impressionable kids ate a fruit He left sitting well within reach, and might as well have written Eat Me on, and did the nasty would at least make some sense - although it would smack of a total setup and/or hardcore pettiness.

I can understand the idea of changing Adam and Eve as a punishement, but why all the rest of the animals...?
