But if you aren't reading religious texts and praying or participating in religious dogma or whatever; chances are you don't believe in a god.
I don't think that participating in religious behavior is a necessary condition for believing that a god could potentially exist while at the same time believing that a god could potentially not exist.
Obviously if the sky parted tomorrow and "THE GOD" appeared and made it perfectly clear that "X" religion had it right I'd get on board with that religion pretty quickly.
But absent something like that, and with the understanding that I'm simply entertaining the idea for argument's sake that some god does exist, I see no compelling reason to believe that any particular religion, or any religion at all as far as it goes, has it "right" in terms of what that god has done in the past, what that god may want or expect from us, what interst that god may have in humanity, or anything else.
Again, assuming for the sake of argument that there is a god, I find it just as likely that he "created" us, because that's what gods do, and then moved on to the next project, and hasn't given us a second thought since.
My five-year-old colors in complete coloring books because that's what five-year-olds do. He doesn't feel any need to go back and tinker with his already completed coloring books, keep tabs on their morals and behavior, expect them to worship him, or any of the other things religious people expect from, and believe they owe, their creator.
I think it's perfectly possible that god can exist completely seperate from and outside of religion, and that religion can exist completely seperate from and outside of god.
