The "First Sin" these people would fear so much, bad enough to cast man from Eden forever and damn us to a mortal life away from God, was just knowledge. That Adam and Eve were no longer simple, naive children that would never question anything was beyond redemption apparently.

That the whole thing is more likely a parable for the loss of childhood (ie Eden) as one moves into adulthood is lost on these idiots. Fucking Barbie tells the same story without people tearing apart society or killing each other over it.
