Debate on 5 Non-Biblical arguments for the existence of God

I always used to ask myself, who created God? Where did he come from?
But for some strange reason we almost feel like we don't have the right to even ask the question.When you start to ponder on it, your head feels like its going to explode. I just shake my head and say it had to have come from somewhere. What was it? It was just always there, the Universe, continually expanding and collapsing? What purpose does it serve?What's outside the big bubble right before it reverses direction and collapses, if it even collapses.Great, I got a headache now.
