A few years ago I started having ongoing debates with a friend about whether the existence of an afterlife is scarier or less scary than there being
no afterlife. She was devoutly religious--Mormon--but she said about once a year she would wake up in a panic, thinking "OMG what if I'm totally wrong and there is no God!?"
She said she has to force herself not to think about this possibility because it freaks her out so much. As she was telling me this I started laughing, because apparently I'm insensitive in the face of another person's most terrifying vulnerability.
Really, though, I found it so funny because my whole life I have literally had the exact inverse of this fear. When I was a kid I went through this phase for about a year where the thought of living forever kept me up at night.
"What will I even do,
forever?" I remember thinking. "Eventually I'll run out of TV shows to watch."
I got to a point that I had to force myself to stop thinking about this because it was not productive.
I told this friend that I could not relate to her fear because what she's essentially contemplating is the possibility of a thing
you can never possibly confirm. Because the only way to find out there is no afterlife is to die and cease to exist, but if you cease to exist you can't know, well,
anything. Because you no longer exist.
