More than just brain chemicals
to Gullibility Kills:What people claim to be life after death is really the chemical process of the brain shutting down.

If that is the case?  Please then explain the millions of people around the world,  who can describe events that were happening during their death,. They recall leaving their body looking down high above it .How they can describe in great detail seeing people trying to revive them or how they are able to travel to see family in other locations.  Those who have crossed over, their stories relate and match to many others who have had near death experiences.
