Do Near-Death Experiences Prove the Soul Exists?

Daylight Atheism examines the research of Sam Parnia, who "carried out a study in which he interviewed all survivors of cardiac arrest at his hospital over one year," and concludes:

Parnia's study...doesn't prove anything about the timing of NDEs or demonstrate that they occur while the brain is nonfunctional. The only conclusive way to prove that they result from the soul leaving the body would be for people in such a state to gain information they couldn't have accessed through ordinary methods - but as I said earlier, aside from unverifiable hearsay and anecdotes, this never happens. Every careful, controlled experiment set up to prove this has turned up empty.
