Actually I did read your post and understood your point. When I wrote "If God/FSM exists, who or what caused Him to come into existence?" I didn't mention "when", or a concept of time. In other words, I am highlighting the cause/effect issue, not the before/after issue.
My point is God's existence did not have a start and won't have a finish...thus the cause/effect doesn't come into play...the concept of "when" has a bearing on cause/effect...if "when" is "always" then there is no cause/effect in relation to God...cause/effect only comes into play if there is a beginning and there isn't with a God...or so says the bible...
Hence why you cannot use "time" in this equation as to "who created God"
