When I was a true believer, the one thing I feared more than anything was being destroyed by Jehovah God at Armageddon. Thank goodness it's all a load of bullshit.
I've got my life to live, and when I die, I die. I can take that. Any kind of afterlife is a bonus. I kinda hope there is an afterlife. Not for me, but for my mum. She was paralyzed from the neck down due to a stroke at age 44, and died at 51. She didn't deserve that. If I die at 70 or 80 then fine, I will have had my life.
BTW, I don't believe in evolution, I accept it because I value intellectual honesty.
