One further point on the subject of psychology and discussion of the "supernatural" (a misleading term, since for many, what is being described with that term is perfectly natural). The only thing psychology can do and has so far done, is to show that there are possible explanations for some phenomena that some people describe as "supernatural". They have not produced any evidence that there cannot be other explanations for these things, or that it is necessarily any more likely that their explanations are right than the spiritual explanations, nor have they produced alternative explanations for all aspects of these phenomena.

So even psychologists and people who study the brain have not provided any scientific or rational basis for anyone to deny the existence of a god, or of any other sort of spiritually based understanding of reality. They have only demonstrated that belief in the existence of those things is not based on rationality or science. It is still necessary for someone to employ belief in order to deny the existence of god, spirit, or the "supernatural", and such belief is also not rational or based on any kind of science.
