Through millions of years of natural selection, we were built to be a sponge as a child and listen to what our parents tell us at a young age. If they tell us not to talk to strangers, we don't. Those who didn't soak in the information or trust their elders would die, and thus be weeded out of the process over time. Unfortunately religion got mixed into this, and MOST religous people were indoctrined at a very young age. Society has accepted religion as second nature, so many kids never question their beliefs as they grow up.

This is what many biologists believe, those who studied evolution and natural selection of human beings.
