Roman Catholic
My own belief system, though one stemming from a non-specific but basically Christian background. In my family, religion as a whole isn’t so much deliberately atheist or agnostic as simply… unimportant. My grandmother on my dad’s side is the only person who ever even mentions a god (she’s a Catholic that prefers to attend a Unitarian church).
So I was left alone to come to my own decisions. I decided early on that I believe in a creator of sort, though not one that ever interferes with or takes any notice of anyone’s life.
I get a little insulted when people assume that means I’m a Christian. The whole Jesus thing just never made sense to me, and it seems like that should be a basic requirement to being considered one. 
Atheist.
I definitely believe in a higher power. I have floated about in my life being Christian, but got turned off by some of those who call themselves Christian. Then I became Pagan, but got turned off by all the flakes. (“Ooooo look at me, I am a PAGAN, I am a WITCH, I am SO SCARY!”) So now I just worship and don’t worry about what other people call it.
I’m an agnostic who believes in ghosts and sometimes hopes he’s wrong (but that so are the Fundamentalists of all faiths). I’m not so much an atheist as I just haven’t found the right god yet.
I don’t know if there is a creator or creators. I don’t know if there are higher beings that do care or don’t care about us. I don’t know if there is an afterlife.
I flip-flop on these issues often.
I believe in science but deep down where the kid in me still lives, I believe in Santa, Nessie and that 2 objects of different weights didn’t always fall at the same speed until Galileo convinced others that they did.
I would like to believe that the Goddess Brigit still dislikes the fact that the RCC took her followers by creating St. Brigit. I like to believe that King Arthur lived. That Tolkien just interpreted the RedBook of WestMarch and Eru did create the world with 3 songs.
Then my damn rational mind kicks in and rains on my parade. The more rational and the more analysis I apply, the more I don’t believe in “God”. Confused and unsure on these subjects is how I go through life.

atheist.
I couldn’t believe in a god if I tried.
Christian. It’s impossible for me to be otherwise.
Catholic (and a practicing one at that, with partial thanks to TomnDebb)
That isn’t a bad description of me.
Guess how I found this thread.
Quite agree.
I do not believe in God. Antitheist in that respect. Not so sure about the gods. Tend to be Buddhist/Daoist in practice, with a dash of Hinduism and animism.
Functionally atheist, though it’s pretty much by default. See, I wasn’t raised religious, never went to church, therefore I was never trained to believe in a higher power. The only way I could convert to something would be if a god materialized behind me and kicked me in the ass.
That said, I don’t think it’s impossible for gods to be created by their believers.
Very liberal non-denominational Christian.
I like to tell people I’m a fallen-away Catholic, because in my twisted mind it sounds romantic. Basically it means that I like going to Mass, singing hymns, and just the general ambience of the whole thing (guilt and angst and pretty angels), but that I have my doubts as to the dogma. Maybe I would fall under agnostic-theism as well.
