Whether you believe in God or not comes down almost entirely to how you were raised. People do not, as a general rule, change their foundational beliefs in adulthood. Except perhaps in response to trauma.

The same is true for other systems of belief: belief in the State, belief in authority, in public education, in fiat currency, etc. It may take a generation to see the overthrow of these institutions, as it is only now that children are being raised to question them.
