You do realize that a vast majority of religions include demons, heaven, and hell? Buddhism, Islamic faiths, etc . . . All have some form of punishment awaiting the bad people in the afterlife.
Also, 13 million years? Before making a counter-argument to OP's discussion, or anyone's before that matter, please do more research.
You contradicted yourself in your post. Ghosts are a belief that there is some reemergence of life, or consciousness after death. Whether it be as minuscule as it is, that's a belief in the afterlife. That is a belief in life after death. And I will prove your statement on people having no evidence of ghosts wrong.
