It's a spritual/soul thing.
The burden of proof is on you to prove the connection between this and god.
NDE's do not prove god in anyway, shape or form.
As I have mentioned, to prove the survival (or soul) hypothesis would discredit humanism...
Since all atheists are humanists (and all humanists reject rebirth/survival/spirit), then accepting the survival hypothesis is the same as accepting that all atheists (humanists) are mistaken.
Since there are only two possible answers to the god-question: either atheism or theism, then
The mistaken answer/category is atheism/atheists, and therefore
theism is the correct answer and god exists.
I point you to Phoenix Journals to learn about the connection between god and soul...
