As for proof - very difficult. I have read several books on NDEs and at the very least it is thought provoking.
One of the books was written by scientists who approached the subject from the scientific perspective - and they successfully debunked a number of the NDEs mentioned.
But in the end, all of the scientists were of the opinion that "something" survives death - even though they were not religious and perhaps had a pre-conceived idea on the subject.
There is only one way to find out for sure ........
