Moses, the liberator of the Hebrews, was a skilled magician. I believe it all started with a golden snake, one that is revered among magicians. His staff, I believe, was originally a golden snake. Anyways, the story of the first animal – one day Moses was in a pretty good mood and someone decided to open their big fat mouth, and so he permanently lost it, waved his hands around in complete angry, and was like HUZZAH and wham, first animal. Also, i think animals are just families of humans that are cursed. By magicians. Think of that next time you eat a nugget.
