Legend,
But here's the thing, do you really think you can take people with "near death experiences" seriously? Think about this for a minute, what happens when a person actually dies? Their heart stops beating and then shortly after, their brain shuts off completely, correct?
Now, in your brain is basically where everything on this side of "life" happens, even when you are sleeping such as the dreams that you have. So what you see, taste, smell, hear, touch, dream, vision, when you walk, when you talk, when you breathe, etc, etc., everything that is being a HUMAN is dominated by the brain.
So an NDE can only function within the brain Legend, listen to the people giving their NDE account and they will talk about great emotions that they "felt" (brain function) and the different things they saw (brain function). The people were near death, they were not dead. So their hearts were still pounding which meant their brains were still working. Basically, what I'm saying is that ALL OF THAT was just in their damn head, it had to be Legend, based on how the brain operates.
Now, does this mean there's no heaven or hell? Not necessarily, I tend to believe there's a higher power, but what "religion" explains about the higher power makes absolutely NO SENSE. Such as how when you get to heaven, you are going to see (brain function) your dead family members. How in the hell do you SEE anybody when you are dead, if your brain is no longer functioning?
We are made up of matter obviously, which includes our body parts and brain, but we also are made up of ENERGY. When they refer to our "spirit" are they talking about our energy? Does our energy have a certain type of brain to it?
