I don't believe all the religious BS about some divine afterlife determined by what you do on earth, however I cant accept that I simply cease to exist when I die.
Think about it, those of us that have rejected religious teachings in favor of science, and for good reason, might overlook one thing. The only thing I am 100% completely certain of is my own existence. Everyone around me might be just be a type of vivid dream that doesnt really exist for all I know, ala the Matrix, but while those plugged into the Matrix were living a lie, they still had a conscious. I cannot accept that something as unique and special as self awareness simply ceases to exist. It is something more than the sum of our parts, ie amino acids, proteins, neurons, etc, and I have no doubt that some part of it transcends my death. I like to view my existence as being akin to fish in a fish bowl. We can learn as much as possible about what exists within the confines of our environment, but eventually you reach the edge and can only hypothesize about what exists beyond it. It's not just the edge of your physical existence, it's the edge of your reality, and every end has a new beginning. Attempting to claim with certainly to know what it is is just foolish, and is usually born of fear. I found peace when I chose to let go of all the religious BS, and accept that I have no idea what happens after I die. If it's simply nothingness, that would be a shame, but no sense in being afraid of simply not existing, though if "YOU" could simply cease to exist do "YOU" even exist now?
