I would like to say that a god or gods don't exist, but I'm told by other atheists that I can't be sure, so even most of us want a little wiggle room. Present party excluded.
So I voted "not likely".
What I pay attention to when god claims are made is that almost all (scientology would be an exception) are old stories, from old times, past on with old ideas and old values. For whatever reason, I am expected to understand that this god character hung around and took direct action for awhile, then backed off and left us to fend for ourselves. Or some variation of that story. And I just can't buy it.
I am expected to read Greek myths and say "Well, of course, those aren't true" but then read the bible and say "Wow, this must be true!" I can't seem to do that.
Were new god stories being transmitted on a regular basis, like UFO sightings are, then I might have a slightly different POV. I'd probably think it was a conspiracy or something. But nonetheless, having only old tales to go by, and no sign whatsoever that a god has been involved in any way (other than those old stories, of which there are many, including gobs of non-christian ones), I go with the most likely scenario. They were all made up. At a time when gods were important for explanatory and control reasons. They aren't needed now. So we humans can stop with the fairy tales.
I also contend that a real god would be able to help conjure up stories about him and his expectations, rather than having a version that sounded so much like all the clearly fake god stories. (By fake, I mean, in this case, fake to the believer who thinks his or her god story is true.) A real god who requires belief just the way fake ones do, a real god who is just as invisible as the others to people today, a real god who is as indifferent to his own followers as he is to those who don't believe would be too pathetic a character to actually exist.
The day some religious group starts enjoying demonstrably better lives, with longer life spans, better heath, more prosperity, few social and personal problems and has an infinite supple of iPads, I might reconsider. In the meantime, all religions are clowns on this bus. (If you don't know who The Firesign Theatre was, that last sentence probably sounds weird. Live with it.)
