yes. I see it regularly. Children start to become parrots of their idols. As adults assume they were always that way.

I think that experience mostly leads to nonbelief.

We all build our own patterns of meaning and patterns of action based on our interpretation of events and experience. That is what enables us to deal with the world we interact with. In general, the vast body of psychological evidence shows that we act our way into believing, not vice versa. We act, see what the results are and build our patterns of behavior accordingly.

My own personal experiences have certainly lead to my lack of belief. All religious stories and anecdotes appear t have very little basis in fact or science or even logic and the contentions of various religions are, to me, quite ridiculous.

What is life but a long path that teaches us what to believe? I mean, no question we get it wrong sometimes. But evolution has kind of designed us to learn how to not die and adjust our beliefs accordingly.

Yes. Every time I accidentally sit on a fire ant colony my butt and legs get horribly stung leading me to believe if I want to avoid getting stung I need to not sit on a fire ant colony.

I think it's a total lack of experience that leads to beliefs.

Lead to religious beliefs? Yes and no. We are often indoctrinated by inherited beliefs--no experience necessary. Unless you consider childhood indoctrination an experience in itself. At other times, we have experiences that might seem useful to us for framing new beliefs around (or reaffirm previously held beliefs), if those new beliefs are are considered to be useful/efficacious in themselves.
