Almost. I think maybe you just don’t esteem nature as highly as I do. I’m not saying what gives rise to God belief can only be the natural world as you conceive it.
The supernatural category only arises when you try to reconcile where this something more is in relation to ourselves and our world but the better we get to know the world the fewer options there seem to be. What do think is the meaning of “supernatural” which most Christians hold? I’ve heard it described as a separate dimension. Why not consciousness? I guess it is because you believe you have authoritative knowledge of who and what God is that you feel compelled to just make up a category like the supernatural.
