Hi doma,
Well, I think you have a different view of what science is than I do.
Science creates a body of explanations for things that are measurable.
It doesn't encompass everything.
Indeed, unexplained things represent opportunities to develop science.
The example you cite is curious for a variety of reasons. Not least that he was apparently dead for 1 1/2 hours. But even if the facts surrounding his case were true, you are still dealing with an unmeasurable, untestable example which could be explained in a variety of ways, one of which is that he experienced what he experienced and another is that he imagined what he experienced. How do you advance science with this?
