I have come to believe that newborn children are completely and totally devoid of any faith. If a child grew to adulthood without mention of any code or creed, would it ever adopt any religious philosophies? My thoughts and feelings tell me no. Religion is something that is taught by trusted adults and almost never something that is adopted by an individual.
As is language, music, cooking, manners, philosphy, aesthetics.....list goes on.....
Also, don't forget, religion is there because humans have a need for it. Many think the need has gone away. It hasn't.

This is interesting from the perspective of a practising Buddhist who was born Christian.
If someone asks me whether God exists, I will say 'it depends'. And what it depends on is, who is asking, what they mean by the question, what they think God is, or isn't. All of this is usually bandied about as if it is perfectly clear what is meant by 'God'. I don't think anybody has any idea - nobody has the remotest idea. What they have is a colection of memories, arguments, and attitudes, which they think corresponds to something that does or doesn't exist.
My attitude is that I don't believe that God exists, but I am not an atheist. I suppose that makes me an agnostic, and I guess I must be. There is a great deal that is unknown about the most basic things. In that great big space of the unknown, all kinds of things are possible. I rather like that feeling of not knowing. But I have also known holy people, people who have been touched by the divine. They are not making it up and they are neither delusional or mendacious in my view.
It's a big world, and we don't know half of what's in it, or beyond it, for that matter.
