Are You Aware of Near Death Experiences?

Near death experiences, or witnessed love ones dying, can be extraordinary. Why are these experiences still not enough for some people not to be afraid of death? The fact we're naturally averse to death is in all organisms that don't go extinct. Modern science has an anti supernatural bias that has discouraged investigation into these and so that's one thing that deprives them of some of the comfort value they could otherwise have. And then there's the fact that some people just lack faith. They don't want there to be in after life, or they aren't willing to make that leap.
