God did create another God. His name was Adam (assuming we are working within the bible framework). Maybe not God exactly, but Adam was certainly the first domino to topple. Don't think God meant to, and I don't think he was too happy about it. "Give me a long enough lever, and a place to rest it, and I will move the world." What I think Archimedes is trying to say is that humanity, through extrapolation of the physical and universal conditions, is God. It's our unavoidable potential for being great.
Think of it this way; the common definition of God is one of supreme power. God sees all and controls all, or some prattle of that nature. The goal of theory is to predict all. The goal of practice is to control all. If some all powerful being created us, he created another God because we have knowledge. That is assuming a comet doesn't ruin us before we get off this rock...
Can God create a rock too big for himself to move? Sounds like a challenge to me.
