Been here many many years....likely from the beginning and I rarely post but enjoy most of what I read. My sister died of Lung Cancer 5 months after her diagnosis. Chemo and radiation did nothing but kill the healthy cells. I am still in shock, because wednesday we were still having a solid conversation and by the weekend, she was incoherent. I saw her lifeless body in front of me on monday and couldnt believe she wasnt here anymore. My serious question to anyone willing to answer is this:

How do we know there's an afterlife? How do we know it isnt just our mind designed by nature to show everyone whom dies the same tunnel, the same beings of light and the same life review for the short period of time the mind is still functioning? I chose this example because it is a common one. I was raised a Christian, and left religion behind years ago. I find I am a spiritual person, but I am having doubts about existence. I want to know if I will ever see her as my sister again, or if that is over, or perhaps she awaits in the afterlife? I spent everyday talking with my sister for years. I am 47 and she was 46......way too young....
