Evidence: The Gathering

[Angrboda]

The International Association for Near-Death Studies sent out a questionnaire in 1992 inquiring about those who considered themselves to be near-death experiencers. How close had they been to physical death when their episode occurred? ... 37 percent had theirs in a setting unrelated to anything that could be construed as life threatening. ... The 37 percenters claimed to have experiences every bit as real, involved, and life-changing as those that happened to people during death or close-brush-with-death crises; and their reports duplicate or parallel the same spread of scenario types and a pattern of psychological and physiological aftereffects.

— P.M.H. Atwater, The Big Book of Near-Death Experiences

Near death experiences are only evidence that some people confuse "near" death with "after" death.

They are proof of nothing but that the brain produces interesting imagery under certain conditions. Interpreting those images to have something to do with being dead is nothing but baseless speculation. The speculation that they are images of post-death experience become the grist for which the images themselves are evidence. That's circular. The speculation is evidence of nothing but the fact that some people speculate such things. The images could have any number of causes unrelated to life after death, and as shown, do not even require near death experience.
