Why have people got inside their head that the afterlife has a connection with god? Maybe the afterlife does exist, if it does, what makes people think we will suddenly know everything and see god?
Because...
Not even the diehard skeptics doubt the powerful personal effects of NDEs.
http://www.near-death.com/evidence.html#a31Proving the afterlife, does not prove god in any way.
So where is YOUR
non-god explanation for the afterlife?
To prove the survival hypothesis would discredit humanism; since all atheists are humanists, then accepting the survival hypothesis is the same as accepting that all atheists are mistaken.
Also...
Because NDEs have many common core elements, this suggests that they are spiritual voyages outside of the body. Also, if the dying brain creates NDE illusions, what is the purpose for doing it? If our brains are only a high-tech computer-like lump of tissue which produces our mind and personality, why does it bother to create illusions at the time of death? If everything, including the mind and personality, are about to disintegrate, why would the brain produce a last wonderful Grand Finale vision? Even if NDE elements can be reduced to only a series of brain reactions, this does not negate the idea that NDEs are more than a brain thing.
