Satanism comes from Satan and Satan is the being in the Bible who fell from grace. You can't take terms and change their meaning from what they were originally intended as. Satan is the author of confusion of twisting and redefining terms illogically. It's like you are trying to gain some credibility from the Bible by using certain Biblical terminology.

You should stop believing in some magical infinite regress or something from nothing in order to reject the uncreated Creator. These ideas are proven false.
