No its science. We now know that many near death experiences are similar due to chemicals in the brain.That is what foolish, uneducated people on this subject matter tend to believe. That is wrong thinking however but they use it as a defense mechanism to avoid facing the truth. If it were as you say then how would doctors, scientists and others be able to explain the fact that those who have a NDE can know what was being said while they were clinically dead? And how would they explain that they were able to "see" what people were wearing and what was going on in rooms down the hall from where they were lying still and dead at the moment among many other things that are unexplainable? You see, with the scenario you have presented it would not be possible to do those things that are reported from all over the world. However, during a NDE the person's spirit momentarily detaches from their physical body and has the great capacity to wonder into other places during that state and can pick up information that they reveal when they are brought back to life or resuscitated.
