Define "Creator"
Um . . . the creator of the universe? And if you're going to say "the word 'universe' includes everything in existence, including this theoretical creator, so He simply a part of this 'universe' that he allegedly 'created'" . . . we'll just call it by its Hebrew name: ha`olam. As a matter of fact, it may even be `olamim, since HaShem is sometimes called Ribbono Shel `Olam (singular) and sometimes Ribbon Kol-Ha`Olamim (plural).
How about the phrase "qoneh Shamayim va'Aretz, which literally means the "acquirer" or "purchaser" of the "universe." Meaning, HaShem "acquired" the heavens and the earth by creating them.
Is this the purpose of all this to demonstrate that logically there is no "creator of all that is" since G-d Himself would be a part of that and that therefore we're all following G-dless, rational morality whether we realize it or not? Or does your whole argument rest on the assertion that G-d being "the author of His own Existence" is no different than than the universe being the author of its own existence?
Please take time to answer my quetion about the big bang.
