Nice quote, kind of a reverse Pascals Wager. :)
I'm technically agnostic, but I tell anyone who asks that I'm atheist. I'm convinced that no god that's presented to me by another person can or does exist. That goes for any god proposed in any book written by people as well.
As to whether some kind of non-interventionist creator made the universe and maybe even has a plan for the future, I don't know and can't know. Some people call that "Ignostic" but I think there's enough confusion going on as it is without bringing in made up terms!
I feel that this has brought me closer to "truth" and I feel more comfortable now that I'm living according to my principles. If I die and against expectation, find myself before the throne of god, I will feel confident in saying "Dude, you have some seriously bad PR guys down there on Earth."
