^I'm not following your 'if THIS than THAT' logic in the first paragraph there. I don't think theism is as grand as you put it, I feel like its simply a belief in a higher creative power that controls reality.
I just don't buy the idea that the big bang is god, or was manifested/kicked off by god. Its an incredibly indirect way of creating something, to leave it entirely to chance. Our evolution tells us that intelligence is not needed to create complexity on earth, and I don't think this premise changes when looking at the broader universe. The universe appears EXACTLY the same as a universe that is designed to look random.
Interesting post, what bits of it my simple mind could follow.
