Just curious, why the obsession with NDEs?
to me that is the best evidence of a possible soul. If debunked, I wouldn't believe in souls.
If I can be helpful. In our study we found "Soul" in it's overall application equates to -person. It's more of---person in connections to emotion. The idea of one dying and going to heaven would be disputed by the apostles who forward---the dead are consensus of nothing.
I also think NDE has to do with chemical or oxygen depletion.
