Please explain what you mean by "[nothing] is necessarily inevitable"?
Are there any episodes in your childhood where you experienced something transpersonal? I had a handful experiences, as a young child, with what I now believe to be meditative states of consciousness. I think whatever is "god" is an inward, subjective experience, which is expressed in our character and way of living. Stamp on whatever appellation you like, be it Yahweh, Tathagata, or wisdom, it's all made up of the same unspeakable material.
