Near death means near death. None of these people died. If they did, they wouldn't be able to explain their experiences. All this proves is high brain activity, that's it. None of these people were brain dead, if they were, there wouldn't be anything to experience anymore because they would be gone. Check the definition of death, please. It applies to none of these people. If the possibility of afterlife makes you feel comfy, okay. I get it. But don't present these subjective stories as evidence for it.
Also: cultural difference is a very strong argument against afterlife. Christian people experience a christian afterlife, muslim people experience an islamic afterlife, hinduists experience a hinduist afterlife, etc etc. You get my point. People all over the world experience different stuff based on their religion or culture. Why is that, can you answer that question? Does every single human on this planet have their own version of afterlife? You know that's nonsense. There is nothing awaiting you once you die.
