The real issue is whether or not you and I have a soul (something that survives death). Apparently, even evolutionary biology thought it was so important to at least create the illusion of an afterlife, that near death experiences are triggered when the heart stops (in some people anyway). What is odd about near death experiences, is that when the heart stops, the brain stops working. If the brain stops working, then consciousness stops working. Right? So why do people experience hovering over their body, have their life reviewed, meet dead relatives, meet angels/God/Jesus/beings of light? How is all this possible when the brain isn't working? It's like unplugging your computer, but it still works.
