In the beginning God created The Big Bang, which created the universe and of course earth. However in the making of the universe something went wrong and a reaction took place, creating magic. Magic spread everywhere but it seemed to be particularly attracted to living organisms, so most of it ended up on earth, settling in animals. Such animals as dragons, unicorns, griffins, hippogriff, creatures pure of magic.
Over time God created humans, his proudest creation of all. The Bible says there were two humans; Adam and Eve, but actual fact there was three! Nobody is sure what they were called or what sex they were, the only thing we know for definite is what each human believed in, each belief related to magic.
Now these three humans learnt about magic through the surrounding magical creatures, and soon enough magic started to attract to them.
One was scared of magic tried to block it out, even when it was under their nose. The other appreciated magic and used it in a good way, teaching their descendants how to use it in a wise way, helping with their daily lives. The third was evil and used magic in evil ways to make them more powerful and to kill people, this person was using magic to discover terribly evil things.
So there you have the three main humans, over millions of generations they developed their powers and went their own separate ways, oblivious to each other. There were times when they met and had battles but soon those were forgotten.
The three humans had plans for their lives and the generations afterwards.
The good magic people had given themselves names, wizards being male magic humans and witches being female magic humans. Their ambition was to teach as many people as possible the ways of magic and try to banish evil magic from this world.
The non-magic folk had rather boring plans, try to build on their cities and ignore anything out of the ordinary.
However the evil crowd had one main thought in their mind, to become immortal and down their road of discovery would find a number of evil curses to torture and kill their surrounding humans.
Over countless billions of years each type of human grew, mixing between each other. Magic branched out to different sorts, like prophecies being made, magical sports, transforming the human body, using magic to help our everyday lives and using magic to cure and help those who were ill. So that now brings us to today, the time of Harry Potter.
