Yes, most people believe in a God or gods of some sort but they don't believe in your God.
You've both repeated this a number of times but I'm not sure that it is true. There are a number of theologians and practitioners in the major religions that would say it is all one God. I don't know the numbers.
However, don't Christians also believe that Jesus is God? This is
not believed by a majority of the world's population. Their experience with God has told them that He is not.
In addition, what does this one God (if that is the case) tell everyone? The same thing? No, they are told rather different things about what is wanted of them. So which is correct? Is the one God lying to some and not others?
