And every time somebody tries to give a definition, you say, No, that's wrong. Then you come back with yet another demand for a definition.
Obviously, they will give their definition, not yours. And they didn't make up the definition. Every time you ask: "What is it you don't believe?" they cite the god of the religion(s) they have witnessed, as described by the literature of those religions, or as told to them by believers in the god.
Simply: In the context of the OP, the god named and described in the Old and New Testaments is the one most Americans either believe in or say they believe in.
What I do not believe in is that one, along with all of the other gods of all the religious not mentioned herein (and yours). I don't need to name and define them individually, because the people who worship(ped) them had already done so, and their literature is available to study, should you require particulars.
