why some people don't believe in life after death If there is no God,there cant be a spirit world for life after death to happen.Christianity,islam,judaism say there is resurrection or immortality of the soul.Hinduism,sikhism,buddhism say it will be reincarnation if there is a life after death they would all say the same thing.Most of the evidence is based on holy books but hey all contradict each other.there is no way of deciding which holy books are true or false.Evidence Of the paranormal has been challenged by scientists.Most beliefs about LAF think that he mind or soul can survive without the body,but science shows that the body cant survive without the brain so when the body dies the mind must also die.there is no place where life after death could take place,space journeys have shown heaven isnt above the sky.people who have been brought up atheists believe there isn't life after death.
