What if God and Satan ( principalities in Chrstian speak) as you know them don't exist?

That is a very good theory. It is possible that evil and good are one of the same. I find it quite interesting. If this was true, then the whole notion of a struggle between good and evil, God and Satan, would be a false belief. This would lead to a collapse of a fundamental concept in the christian faith. Most Conservative christians would not even consider this theory. However this is a very good concept and I believe it can rise some interesting debate from not only christianity but all abrahamic religions.
