I only believe in hell in the practical sense. I think that there are many "hells", found here on earth and other inhabited planets we don't know about. For example, your workplace can be your own personal hell if you feel it sucks enough.
When you die, your brain activity stops, so you're DEAD dead. You can't think or feel or anything, and you won't need to. Some people take comfort in the thought of life after death, but they shouldn't need to. When they're dead, there's no need for any afterlife. For some people it's actually a very comforting thought that death takes them back to where they were before birth, which was nowhere. Not everyone likes the thought of an afterlife.
These are merely my personal opinions, opinions because there's still no way I could prove them, I just personally believe these opinions are based on what I believe to be common sense, and all differing opinions are respected.
Looks like we're not going down after all, so nevermind.
