I am a Gnostic atheist - meaning I have a positive belief that no gods exist, rather than a lack of belief in gods (for those that draw the distinction), and I agree with you. I think that the wiring of our physical brains create conditions which under certain influences will lead to a belief in a god or gods. I don’t think choice comes into it at all.
That doesn’t mean that people cannot have their minds changed by discussion or experience. It just means that there’s causality, but not choice. If you get the flu, it’s not because you chose to get sick. If you have epilepsy, it’s not because you chose it.
