People forget that we were once all part of the same society. The ancient mythos is our record of those times, fragmented and allegorical as it is.
What we define as "god" and what we define as "satan" are all attributes of our being expressed by choice. These are less external forces acting upon our society as they are forces from within ourselves being expressed. Whatever the gods once were, we are the gods. That we can conceive of a god above even our own existence is the realization that a true god lay beyond an ever-expanding horizon as the embodiment of everything we want to, ourselves, understand and become.
