Why is 'truly experienced God' your preferred explanation over the multitude of neural effects that can cause similar things? Do you think something being about 'the future' or any confusion of space and time doesn't happen to people having strokes, epileptic fits etc?
Or ingesting 400 milligrams of mescaline? I did that a few times in the long-ago and had some very nice "religious" experiences. Brain chemistry, Hawkins, is the parsimonious explanation for stuff like that. Dieties are the unevidenced explanation.
