So I haven't read the last 16 pages. My thoughts on God are rather simple:
1. We have no way of knowing whether he/she/it exists or not. Some people derive faith in a any number of deities for any number of reasons, some don't.
2. Some people lose faith in God, some gain faith in God. Most often at the same time, during a simultaneous exchange of faith in one thing for faith in something else.
3. There is a stark distinction between faith and fact. The latter is substantiated by human logic, the former is not. One may or may not override the other depending on specific circumstances.
4. The human condition requires faith in something to progress. It's how we're wired. It may be faith in something as physical as wealth, or in something as mind-bending and ethereal as Aristotle's meta-physics, but there has to be something upon which to base our view of the world.
God may or may not be an outcome of this need.
5. Some require God more than others.
As for my background, I was raised Baptist, became Agnostic, became Deist, and recently consider myself a philosophical Taoist (meaning I regularly read, analyze, and attempt to follow the lessons of the Tao Te Ching).
I suppose that Tao could be considered "God" by one interpretation. It's described as the source of all creation, the place where all things eventually return; and that its essence can be observed but never grasped by mankind. However, in verse 1 it's stated: "Tao and this world seem different, but in truth they are one and the same. The only difference is in what we call them".
Given that the entirety of the Tao Te Ching is poetic and interpretive you can take it any number of ways. But for all the possible interpretations there's a surprising consistency to the traits ascribed. In fact, reading the Tao Te Ching there are surprising parallels to Christian teachings, albeit without all the explicit divine mandates (part of the reason I gravitated towards it).
So I'd say I believe in Tao and you can call it God if you like. I can't say whether it will be accurate, as "God" usually implies a sentient being with a coherent will, and Tao is never described as such in essence.
One thing I am certain of: regardless of the existence or nature of God, the often savage, biting, scraping debates over its existence and nature are a purely human creation born of purely human needs.
