Who really....really wrote the Bible?, page 3

here's my take on the whole religion and bible subject. Not just christianity and the bible, but any religion and/or book of faith.
Basically I believe that books of faith and religions are pretty much like a very elaborate chain story that was written by many people throughout a fairly long timeframe. One person started with a story/idea and it was added to and grew through out time and peoples. I believe that alot of people would agree with this reasoning. what people dont seem to be able to agree upon is , WHY these people thought up these ideas/stories??
Anybody involved in these religions seem to think that there was some sort of devine intervention by whichever higher power they believe in. And that seems to be the ONLY possibility that they accept.
I believe there are many different motives and/ or reasons for the origins of these religions and books of faith. None of which has anything at all to do with devine intervention.
1. fear of the unknown-- it's very feasible that people started to think up reasons to explain away many of lifes mysteries. such as the meaning of life, what happens when you die ect. Who wants to go through life being scared that thier life is of no consequence and that when you die, you just cease to exist in all sense of the word existence.
2. Safety in numbers-- it's human nature to feel safety in numbers. A group of like minded people with the same beliefs tend to congregate in large groups. The reason for this being protection from outside threats be they physical threats or a threat to the way the group as a whole believes and lives thier everyday lives. If like minded people didnt congregate then there would be anarchy and in an anarchy, no one is safe. Thats one reason why religions recruit and convert. the more people that are in the group, the safer the group is.
3. Behavioral control-- All religions have a set of guidlines/rules which its members must live by. This goes back to the safety aspect. If a religions members didnt follow these guidlines/rules then , again you have anarchy.So you lay down these guidlines that have some sort of consequences so that people fear what will happen if they dont follow the guidlines/rules to keep people in order to guard against anarchy.
4. Prosperity/greed/ profit of the like minded congregation -- again to the power of a large group of like minded people. the more people that belong to a group the more prosperous and productive that group is toward meeting thier philisophical and material goals. this ties back to fear that ones life is for no greater reason.

There are other reasons, but i believe that whatever those reasons are and the four I have listed are all entwined and each has a tie in to one or more of these reasons. NONE OF WHICH INVOLVES DEVINE INTERVENTION IN ANY WAY WHATSOEVER. It started with the first primates to walk on earth and has been passed on through the gene pool. Instinct led to emotion which led to thought. the strongest instinct in most any living creature is self preservation. this instinct led to the emotion/instinct of fear which led to conscious thought/instinct/emotion of how to succeed in the most primal of instincts-- self preservation.
This is some of my philosophy on how things are. I know it kind of goes in circles but life is very complicated. hope it made some kind of sense.
Personally I am not scared of death or of the thought that life had no meaning. I have had fun and enjoyed life and its experiences, be they good or bad, the best way I know how. And knowing/feeling that is enough for me.
I welcome any criticism or comments.
