Anyway, believing in the afterlife is fine for some people. What I don't understand is why it is so difficult for people to even imagine that there may not be one. It seems pretty obvious to me. Think about it, of the >99% of the species that exist on earth today which are not humans, we do not think that they go to some heaven or hell. There is no dog heaven, or bee hell, or fern purgatory. So why then, is it so unbelievable that we may not exist beyond our current existence? Considering the major difference between ourselves and those other animals is an awareness of our own consciousness, isn't it much more likely that the idea of existence after life would arise from that self awareness rather than that we have been chosen for an afterlife because of it? If dogs and bees can simply stop existing, why can't we?
The point is, don't act so freakin' surprised at people who don't believe in the afterlife. It's not that hard of a concept to grasp, it's just a different way of thinking. It doesn't make life any less endurable, in fact in my case, it has made it more pleasant*.
*and before you ask, it's not because I feel I have carte blanche to do whatever I want. I'm a good, honest person. So there.
