OK lemme make it simple enough so you'll understand it.
-Where did God come from?
-Who made god and how? Out of what?
-Before God existed, what was there?
Because your answer sounds a lot like "God only exists in my mind because I say so"
I'll return your "simplification favor":
"Act as though I AM and I will be".
Put another way; Is the electrical current which is available inside the wiring of your house less real because you choose not to tap into it?
