The "naturalistic" world, if I understand your meaning correctly, is extremely well evidenced. The supernatural would, on the other hand, is not.Isn't a naturalistic view of the world as unevidenced as a theistic view.
It could be argued that if atheism (non belief) is from birth. then there is no evidence for it and none needed. I imagine many atheists say that.
Atheism isn't a view. It's a lack of view.But of course atheism (lack of belief) is really a naturalistic view and that one is a belief,,,,,,,,,,,,,,with no evidence except for hypotheses of a naturalistic science.
We're all born atheist; all born without any beliefs about anything. Our various theologies and religions are taught to us later.
Atheism is the epistemic default. It needs no evidential support.
