Satan is us making forms, the children constructing play things, the emotionally childish manner of mortal demise. By analogy, it is civilization, music, possiveness, greed, friendship, romance, grief, and wonderment at the world so quickly created and so swifly ripped away (apparently by circumstance). These and others are social forms by which we, as humans, have structured our world. In a slightly broader sense, it is also our conscious existence that creates the forms of the world-as-we-know-it that envelopes us every waking moment. With our knowledge of the world around us our as building blocks, we each structure the world in a unqiue way, no two people seeing the world quite the same way from moment to moment. In the broader analogy, Satan represents the murder of the uniform void by fracturing it into knowable "things", and vice-versa the uniform void is the destruction of Satan (at the end of the clip) and all knowable things.
"God" is many things to many people, but to many he represents some form of a compromise between the void and the world-as-we-know-it. To some "God" appears as the maniuplation, or the thing that allows the structuring (fracturing of the world into "things") to occur in the first place. (First place = prime mover)
