Ok, but that doesn't change the fact that people who explain their personal experiences and how they line up with their chosen belief.
Before we get into NDE's...
In my case, during what I'd call my most important "personal" experiences of God prior to age 15, all of them involved a strong sense of unconditional love and acceptance. Such experiences did not however "square very well" with my "religious" concepts of the time, specifically things like the concept of hell. I could not comprehend how that unconditionally loving being that I experienced within could ever torment souls for the whole of time for the sins that occurred in the relative blink of an eye. It logically and emotionally would not jive with my internal experiences of God, no matter how hard I tried to rationalize it. It wouldn't work.
That eventually caused me to 'question' everything that I believed in, including religion, God, and the whole nine yards. I ultimately ended up embracing atheism for many years.
Those internal experiences however didn't actually 'cease' with my switch over to atheism. I didn't focus on God of course, or do anything in terms of prayer or meditation, but those experiences of unconditional love still "leaked in" sometimes while I watched a magnificent sunset, or felt myself stirred internally by beautiful music.
It wasn't until I got the chip off my shoulder toward religion, and realized I didn't have an honest scientific answer as to God's existence that I could actually sit down and internally *ask* God again if he even existed from a place of honest scientific curiosity. More experiences ensued.
Even after embracing theism again, I couldn't simply "go backwards" into believing in a religion that made no sense to me. This caused me to do a whole bunch of research to see what happened to "Christianity" to find out what changes took place historically.
The religion that I embrace today is really not very 'like' some branches of 'Christianity". I love and honor Christ as my personal Lord and Savior (from selfish ego), but I don't necessarily buy a lot of the standard "Christian" dogma, even to this day. I certainly will never again believe in eternal torment for finite sin for instance.
This even extends to near death experiences, where the experiences line up with the person's individual beliefs.
Culture and Near Death Experience
The interesting thing about NDE's from my perspective is not the cultural aspects (I'd expect that actually), it's the impact the experience has on the person's life over the long haul, along with the fact it results in pretty significant changes in their long term behaviors. They often put unconditional love before anything else, and their beliefs after the experience are often different than they were *before* the incident. There is typically something they have "learned" from the experience in terms of their spirituality that doesn't always jive with the preconceived ideas. These "teachings" (during the experience) cause them to make significant changes in their lives.
The other interesting aspect is that the experiences occurs as frequently to atheists as to theists, and even atheists report meeting "God'.
I should also note that there are mathematical models to describe a concept of "soul" that could, in theory at least, survive the death of a physical form. Such theories lack empirical support in much the same way that dark energy lacks empirical support or SUSY theory lacks empirical support however, so believe in soul requires an act of faith in the validity of those maths.
In terms of pure physics however, it's impossible to rule out such ideas.
