Because religion is laughable

Lions in Eden

The First Couple, alone in the Garden of Paradise and a Commandment involving forbidden fruit.  What could possibly go wrong?

Enter the talking snake, and all Hell breaks loose.  The hapless couple are evicted from Paradise, and Death arrives on the scene. 

All of which I presume pleased the lions admirably, having been equipped at creation with superb canines - which were frankly not well-suited to fruit and nuts.
