It'd be so nice to believe in an afterlife. To believe that I will see my mother some day even if/after this cancer kills her, that I will see my dad someday at all. But I don't. I don't believe that there's a Heaven, or a Hell, or anything like that. I think that when an animal dies, any animal be it insect or human, it's just out like a burnt out light bulb. I have family who walk around funerals saying annoying things like "I'm going to miss him from now until I see him again in the Kingdom" and "it's not goodbye, it's just 'See you later'". I'm sorry, but we are no more complex or miraculous than any other species. We are, as a species, relatively weak and vulnerable. Our mastery of tools is really the only thing we have that they don't, and until you can give IQ tests to fish there's no way to know we're all that much smarter than animals either. SO the idea that a God made us, and gave us souls, and that those souls are so super-special that they can never die, is just arrogance. If biology is enough to explain cockroaches, it's enough to explain us. We're organic life-forms capable of dying, not never-ending invisible spirits who will live on forever with our friends and family depending arbitrarily on our behavior for a mere 80 or so years in the beginning.
I will miss my mother when she dies. I miss my dad now. And when I die, my kids will miss me. But it's not "See you later". It's "goodbye". And even though I truly believe that, I hope I'm wrong. I also hope wishing on shooting stars will work, too. But I don't think either of those are likely or all that plausible. But it would be really nice if they were.
