An agnostic: One who does not know.
Well, if you don't know something, isn't it better to admit you don't know it, instead of, like the kid in class who talks off the top of his head, coming off like an idiot?
There's a lot we don't know, though a lot of people don't like to admit it, and pretend that their own opinions are advice from God. Heck, there isn't even any evidence Jesus existed, but that doesn't stop many people from arguing about what Jesus said or did not say.
You've got your head together, in a more solid place. Be proud of that. You can feel good about being agnostic, which is what motivated us to put this collection of agnostic gear together in the first place. We celebrate uncertainty!
