I prefer to call Satan the [a href="http://en.wikipedia.org/wiki/Demiurge"]Demiurge[/a].
According to the Gnostics he is the creator of this universe and feels himself to be the one true god. However, he is not the one true god as christians misunderstand him to be.
Jewish Kabbalah, the great mystical philosphy of the jews, calls God the ain soph aur. Rough translation: the ultimate limitless light. This God cannot be known and anything we think we know about him is wrong and possibly blasphemous.
Anyway. Gnostics believe that we all have a divine spark within and this is our path to the real God. As above so below.
