I'm not too familiar with that subject, but I would take "god" out (since that's a complex word in itself), and think more of it in context of god of the gaps: finding practices and ideas to explain the natural environment, their place, and the relationship with people they are around and associate with. Another thing is that way back when we were polytheist not theist. I think I learned in art history that the one-god (one-king, one president, one truth, etc) are all political to emphasis authority over people. Though this is entirely cultural, it still makes sense regardless.
The problem is trying to fit our idea of god to the idea of deities way back when. Even people on RF who believe in abrahamic traditions try to fit the concept of their god on eastern traditions and their gods. Even the word god itself is not even universal.
But I'm still confused how you guys don't understand if you're not in an environment to know of god, how would you inherently just believe in one?
I read awhile back in ASL class there was a hearing woman who was raised by Deaf parents in a Deaf/HH town (in Illinois or somewhere close). She thought everyone knew ASL and she never heard a spoken word. When she went to college out of state she was shocked and literally had to learn English to communicate with her hearing peers.
Now, we can say "but she knew English (or other spoken language) because she was born with that ability, but the fact is she didn't know because that's not how she was raised. Take right and left handedness. Most of us have the ability to write, but at one time teachers punished left-handers because to be right handers since the majority=normal. Even the white environment and one black person really tips people off.
So, my point is, it's literally environment, indoctrination, and god of the gaps. Another thing I noticed is as years go on, the more interpretative and abstract christianity seems to be. At first we were dependent on rituals, traditions, and oral stories and so forth now many christians are saying god can't be explained by rituals, mystical experiences, and the like. As if the mundane cancels out the spiritual when in the past (making an intelligent guess on my former practice) it just wasn't so.
I mean, people put their concepts of god today on the bible and their culture, language, and understanding of life and science are completely different than 2 or 3,000 years ago.
