Atheism

[Mister Agenda]

No one is maintaining that the experiences aren't real. They're real experiences. It's their nature that we're disputing. Because religious experiences differ depending on culture, different people interpret similar experiences differently, and the experiences can be simulated with drugs and/or electronics, religious experiences fit the profile of a neuro-cultural phenomenon. Evidence that there is more going on would be advisable before concluding that there's more going on. That is, the null hypothesis has not been defeated.

This is the part I am challenging. If you take the step of saying that the person's experiences are not a result of the supernatural, that is a simple assertion. Any attempt to justify that assertion becomes question begging. Your attempt to introduce a null hypothesis is simply an attempt to sneak in the assertion; since the only way to know of a person's inner experience is to ask them, the concept does not apply. 

If you are able to overcome the null hypothesis (that neuro-cultural factors that we have at least a basic understanding of are sufficient to explain the phenomenon, and incidentally, explain it better), by all means do so. If not, I should hardly take it on faith that you're on to something rather than motivated to insert the Christian God wherever you think it will fit.
