Im happy with my life, dying is not a problem to this atheist. I know {roughly} what will happen to my molecules and atoms. Life goes on.
This is something I have noticed in people in general, especially atheists. If they are happy with their lives then they do not care about any possible afterlife. But that does not seem logical to me, because we all get older and we will all die someday, so IF there is an afterlife, it makes sense to know something about it and prepare for it.'
Most of my close friends are on forums and most of them are atheists. They do not like talking about the afterlife because they do not think there is any possibility that it exists, so I don't bring it up anymore unless they do.
I could make my life better on a material level if I chose to think more about the material world, because I am quite wealthy by most standards and I have good health and a nice husband. I could retire right now and travel the world if I chose to; but I am not interested in the material world, I am only interested in my animals and people I care about, or any other people who I could assist on their own spiritual journey.
Speaking of people, I am really happy right now because an atheist forum owner with whom I had a falling out last spring and I have made amends and he just invited me back to his forum and made a private folder for me and one of my other friend so we could talk privately, away from his other forum posters who used to give me a bad time about my religion. I really like this forum owner, he is a physicist, has a PhD in Physics and teaches at a college. I highly respect him as a person because of his character and he cares about people, society and the environment, things that also matter to me. I do not care if he believes in God, that does not matter. I am just happy to have him back as a friend. I do not have any family except my husband and a brother I never talk to anymore, so friends are really important. Mine are all on forums and for some reason, I gravitate more to atheists than to beleivers.
Back to the afterlife, that is one thing I am sure of. Of course I cannot prove it exists, but there is a lot of evidence, more than just scriptures of religions. Although this evidence is not scientific, scientists are working on that and I think that in the future science will be able to provide some evidence, even if not proof. This new age is an exciting time to be living in and many new things will be discovered. Science is very interesting to me but I was never good at it in college. Geography and psychology are where I made my niche.
