Thanks for the rep - to answer your question, I would say it's clear that the universe has a beginning and in my experience, all things that have beginnings were created. Conversely, my working definition of G-d is that he is infinite - or - always was, always will be. So, in other words, I can "prove" that the universe began, which implies its having been created (as it once was nothing at all) by my common experience. I cannot say the same about G-d. I realize this is a matter of my definition of G-d , but in my defense, if G-d is something less than infinite, he's not worthy of my "worship."
