Theism; yeah. Enough said.
Deism; the chocolate kettle of belief systems. It's there alright but will it do anything useful for you? Ooooo look at the pretty kittens! And God, isn't photosynthesis simply elegant?
Pantheism; to those who remember Pan's People, the feeling you had the first time you saw them at age 10... Oh... My... God... To the rest, thou art god, I am god, the cat is god (especially my cat) that rock is god... well, some are like that to one extent or the other, others use 'god' to describe wonder(?).
Atheism; I still believe in god enough to define myself by the absence of something I don't believe in, so add asantaist to the list too please...
Bright has been suggested as an alternative label. Humanism is used by some but carries with it a not-necessarily-compulsory ethos for other atheists. Buddhism purports to be. I think Nergle is as good a word as any.
Pan narrans. The story-telling ape. Of COURSE we think our individual stories makes sense. We stare at the night sky and see lions and bears, not sure about the tigers, but there you go.
Whatever data points we have to assemble a world view, we end up assembling a world that on some level makes sense. If there HAD been buses when we thought the world was flat, they would STILL have been as reliable/unreliable as they are now. People somehow were born, married, had children and died under the misconception they were being orbited by the sun! You can believe what in hindsight is utter rubbish and still be absolutely convinced your story is true. Because that is how our heads work.
The only way to be reasonably sure we are 'right' about something (whatever 'right' is) is to look at as much information about it as possible, and ensure we comprehend it. Even then, someone turns the page, the story can change.
Quote I read in a Discworld book; "I don't like scientists on committees, they don't know where they stand on anything. Give them new data and they change their minds".
I wish there was a magic smiley that would appear on the posts of people who don't get the joke...
