Late to find this thread
Having only found this thread in what looks like its death throes, I would still like to make a comment on one of laci's earlier claims of which I have had personal experience.
People who have near death experiences do not uniformly see a bright light, nor do they uniformly see a figure from Christian theology, e.g. BVM. Buddhists tend to see figures from the Buddhist pantheon. Hindus tend to see figures from the Hindu pantheon and so on. What one sees seems to depend on one's belief system. However, a substantial proportion of people who "die" and are re-started, like me, see nothing at all. Just oblivion.
Let me outline the steps of dying as I experienced them after a road accident:
Firstly there are feelings of shock and horror, "This can't be happening!!!!"
Gradually one's sight begins to fade, and so does the pain.
Around about this stage the feelings of fear and anxiety give way to a feeling of calm detachment.
Eventually it takes a real effort to focus on anything and as peripheral vision goes it's like looking down a gun barrel. Soon it is no longer possible to see anything.
Long after the loss of sight it is possible to hear. In my case I could hear people discussing how best to proceed and even whether it was worthwhile to make the effort. This was not worrying despite being a life and death decision about
me. A feeling of detachment continued while all consciousness faded away. (By "detachment" I don't mean "out of body experience". I mean a feeling of no sense of involvement in what was happening.)
The medical team eventually decided it was worth trying to resuscitate me some time after all signs of life ceased. In fact I later found that they had used some pretty severe interventions. No problems, I was dead and neither knew nor cared.
As I finally regained consciousness I first felt confusion, then the pain hit me and I wished that I was still out of it.
From that point it was almost four years before I had a fully normal life again. However, I was alive. This was a major plus and infinitely better than the alternative.
The point I wish to make is that near death experiences really can't be used as evidence of anything supernatural. Not everyone who dies and is brought back has a classic NDE - i.e. long tunnel, bright light, sight or voices of religious figure or dead loved one, etc, etc. What people experience depends in large part on their expectations.
There are good physically-based explanations for most of the experiences of the "classic NDE". It really isn't necessary to invoke the supernatural - Occam's Razor Rules!
