Uncle Pug:
Why, how and for what reason did the predilection to religiosity arise in humankind and why does it continue to persists and even thrive?
In other words... what survival/procreating advantage did/does believing bestow?
you are looking at advanced cultures which have religion and extrapolating backwards to assume that all human cultures have always had religion
if you look at the remaining hunter gatherers on Earth (on the Amazon, New Guinea, parts of Central Asia), you will see that they do not have religion in the sense you use that word.
they have a relationship with the natural world that involves the supernatural.
why?
it's a way of explaining the unknown. why does stuff happen? because there are beings we can't see that make it happen. you can explain seasons this way, fire, lightning, migration routes, illness, etc.
in fact, this "proto-religion" is just another technology that the human race has developed, in this case a technology for understanding the unkonwn, just like the wheel, writing, agriculture, etc.
all of those technologies (including religion) were invented independently of one another at quite a few places on Earth, and it shows that faced with similar problems, humans will tend to find similar answers.
then, religion evolved, as all cultural constructions do, and, as Soggy said, it became a tool of control and power projections by the elite, a useful propaganda to keep the masses under control.
which one sounds better?
1. I am the King because I say so; or
2. I am the King because God says so.
1. I say you don't kill one another; or
2. God says you don't kill one another.
if you think of religion as a product (or a "commodity") and you want to know why people continue to consume that product, just ask yourself why you believe in God.
it probably makes you feel like your life has purpose, that you have a higher calling, that it's all worthwhile, and in the end, all will make sense, that you're not alone in the world, that the Maker of the Universe has a special relationship with you and thus you are worth something... etc. etc..
it's a powerful product. it fulfills a powerful psychological need to "be special and be good and feel i am living a righteous life."
in that respect, it can give people a powerful drive to do good and can lead to happy, fulfilled lives (or, its more negative aspects can creep up, but let's put that aside for now)
sort of like diving
