i believe that first, people either saw real magic, or saw what they believed to be real magic... and then after realizing they had no special powers, began to make it look like or seem like they could do things that not everyone could do, not to fool people, just to entertain, to be the "life of the party" so to speak... but there is definatly no true beggining of magic, it just kind of gradually grew and still continues growing. and as people reveal more secerets, we have to improve what we do. instead of just being left to improve if we want to. which is kind of a pain.
