Bingo! Humans created "God" in their own image.
I believe there is definitely a higher power or force in the universe. There is some kind of "cosmic consciousness" or something and many of us feel that.
But I do think that the whole story of God was an attempt to make people understand the force in a way they could relate to, as a sort of big Grampa in the Sky who watches over them. Thus, bad things can be explained by Grampa getting grumpy over the naughty children's behavior, and all the children could be basically terrified into submission to the rules (as defined by men) about what is good and what makes Grampa very angry.
If you are good, you go to Grampa's special playground of happiness, but if you are bad, you go get a spanking the likes of which you cannot imagine.
This is a concept all people can understand, and if they will buy into it, it gives the church (and politicians) a hell of a lot of power.
Amazingly enough, people are still buying into it today - but there are also an increasing number who are finding that source of power and joy outside of the whole "God" story.
