I have a friend who believes that “god” is simply a notion that people invented to explain things for which they could not find a reasonable answer. People are a superstitious lot no doubt, but it seems a valid point to ask if God created us, or did we create Him. The answer to this seems simple enough. Just ask Him! He did, after all, provide a path for finding out.
"And without faith it is impossible to please God, because anyone who comes to Him must believe that He exists and that He rewards those who earnestly seek Him"
