gee, Amos, you bit anyway
..."While the majority of humans on earth have experience with the spiritual at least in some degree,..."

The whole point is that, embedded in that sentence is a serious equivocation on the word "experience". An 'experience' with " NDEs, OOBEs, moments of telepathic or remote viewing, snatches of reincarnation memories, deja vues, and so on. " is in a quite different category than one with a side of beef, a VW Golf, a naked lap dancer or being whacked with a copy of Husserl's Phenomenology.! (grin)

Being 'absolutely sure' that you had an OOB event is a different claim than being sure you had a naked lap-dance or had a side of beef dropped on you.....and...just because far fewer folks claim to have had a direct experience with God, doesn't make the claim more or less credible than NDEs or OOBs...maybe God is just capricious and has a wicked sense of humor!
I, personally, have never had any of those, so I can admit just for the sake of the discussion, the 'possibility' of both types, while seriously doubting both.
