God versus Aliens - why can't they all just get along?
Here's a little test. Imagine, if you will, that you've just been born, fully formed as an adult, but with none of the emotional baggage and preconceived notions which comes from years of indoctrination.
Imagine, then, that someone told you there was a mystical being who nobody had ever had seen or heard, but who created the universe. Not only did it create the universe, but it also has an unhealthy interest in your sex life and will also take personal requests like some celestial DJ
Such a proposition would, under any rational analysis, be greeted with uncontrollable laughter and open scorn.
