Interesting spot you find yourself in aperson !!!
Good luck with your journey.
The only thing I'm wondering about is, why do you feel that you need answers to all your questions? (Thus needing the gaps filled)
No god spot has been proven to exist in the brain, and even if it did, it wouldn't prove a god put it there.
Hypothetically, let's imagine there are people with god spots in their brains that spend a lot of time thinking religious rubbish, and other people who don't (or have a smaller god bit, and a larger science bit). Let's say they both find themselves in Iran. How long do you think the non-religious guys are gonna last? Being religious in Iran is definitely a survival advantage, and the same may have been true throughout human history. Therefore the evolution of god spot, or even just a propensity toward guessing at possible theistic explanations may be a survival advantage, leaving, as usual, the existence of the gods themselves, out of the picture.
Being good to people is how we survive as a tribe, when it gets cold, or wolves attack us in packs, or when the aliens have us surrounded. Think about ants and how their co-operation ensures the survival of the whole nest. It's possible empathy is a product of our imaginations which allow us to experience the pain of falling off a cliff without actually having to do it ...thereby, we learn not to do it.
Being an atheist does not make you immoral. Quite the opposite.

Quote:True morality is based entirely in the real world. "Because morality is a social necessity, the moment faith in god is banished, man's gaze turns from god to man and he becomes socially conscious. Religious belief prevented the growth of a sense of realism. But atheism at once makes man realistic and alive to the needs of morality
Buddhism ain't gonna hurt you none. It's quite compatible with atheism.
