Life Death Experiences

Near death experiences do not show there is life after death. Do you agree? && reasons please?

Questionnaire survey for my RE homework, would appreciate if you could help me, thanks

NDEs are just hallucinations caused by loss of oxygen in the blood. There is nothing special about NDEs.

Furthermore, consciousness is nothing more than chemical reactions. Since those chemical reactions (i.e. consciousness) do not transcend death, souls/spirits do not exist; thus concepts of life after death (reincarnation, heaven and hell, etc.) are null.
