The great thing about the science is that it doesn't matter if I'm impressed by it, or if I like the answer. The answer will not change. Knowing these answers serves only to heighten my appreciation for everything around me. It also helps me to deal with the world. There are people in this world that rub me the wrong way, in fact there are quite a few that I flat dislike. It's important to realize that we're not so different on the most basic of levels. We are made of the same stuff. Our bodies undergo the same processes. The reason I get frustrated with these people isn't that we're different. It's that they often misunderstand what I am trying to tell them.
When did we come up with the ridiculous notion that our lives had to have meaning? They don't. You can give yourself goals and a purpose, but you have no predestined purpose. And what's wrong with that? Does that mean you can't spend your life helping people? No it doesn't. In fact it means the reason that you do so, is because you decided to. I personally think it's much better to want to do something nice for someone than to be forced to. It would seem to me that the greater virtue is in being nice when you don't have to be. If you're forced to do the right thing, then you're not really doing the right thing. You're just doing what you're forced to do. I'm an optimist in this matter. I think that people who bring about good in the world in the name of religion would probably still do so, even if they didn't believe in a god.
