First, I used to be an ardent Creationist but realized that nature does not allow for such a notion. There's far too much that exists that's just horrible - and ( seemingly) Really Well Designed - such as Guinea worms, Crocodiles, Tyrannosaurus Rex and more. A personal Creator would have to be a psychopath and would resemble something out of a H.P. Lovecraft novel.
However, that still allows for a transcendent impersonal God who operates as a system - and might even answer prayers. I think the human race has a perceptual block in that they use the brain as an analogy for a God as Designer instead of seeing "Him" as being more like the body - a marvelous system of systems that needs no immediate conscious direction to grow or exist ( I still breathe and my heart still beats even though I don't think about it) As for symmetry and more, I have one thing to say: Folks, at some level, the universe "just is". Yep, that's right - reductionism fails, ends, no mas..... Victor Mansfield realized this ( Buddhist physicist) - so have some atheist scientists who critique entanglement results ( Victor Stenger) Which leaves me wondering, what in the macro world might "just be"? Ghosts? ESP? Bigfoot? I don't know but I do get a laugh whenever some Great Authority pontificates about what can or can't exist according to some neat, elegant theory of reality. Ultimately, it all, 'just is'. That's why I had no trouble believing that Cold Fusion could be real. Plasmons and such are nice but , in the end, stuff 'just is'.
