"Evidence" is NOT "Proof." Evidence is a statement, writing, material object or other thing presented to the senses. Proof is the impact or "force" of the evidence on the mind. The stories do not really rise to proof. My favorite is the Indian bureaucrat sending the person back due to paperwork error. Is that what you mean by an afterlife? What about the persons who experience Blackness-nothing! I have personally met one of the latter people-nothing! I don't take that as "Proof" that there is no life after death.
To me it is only those who are living who relate their experiences. Those who remain dead do not tell us. There is a VAST difference between the two groups.
