I consider the question, "Is there a God?" is much like the question about which came first, the chicken or the egg. No one I know, really knows the answer, they have many opinions. Opinion usually based on early programing by parents, and influenced by our culture.
I've done extensive studying on the world religions and basically they same the same thing, only in different forms of rules and control.
When I think of spirituality, I think of indigenous peoples. Such as Native American or Aboriginals of Australia. Both those groups seemed more concerned about the community, rather than the individual, with a strong sense of protecting the land where they lived. I was fascinated watching as an Aboriginal identified a tree that had a gurb living in the root system. He would then carefull scoop the soil around the root, then cut the spot before and after where he had identified the grug. Then very carefully he would push the soil back around the root. His explanation was they wanted the tree or bush to continue to thrive so that it might host another grub in the future.
Another interesting thing about their lives, is simply being involved in the moment, not aspiring something more than what they had.
