Size Matters

Now while it's extremely unlikely, I suppose it is possible that an all-powerful God or Supreme Being created the Universe, then waited billions of years before revealing himself to human beings on Planet Earth.

And if we are to believe what competing holy books say, God revealed himself, first of all, to the followers of the Jewish faith before changing his mind and deciding that the Christians were really the chosen people, although this only lasted until 610 AD when Islam was born. 

To be fair this narrative excludes a whole number of offshoot religions which came into being at a letter date such as Mormonism, Scientology and the Bahias, but you get my general drift which is that the Planet Earth and the people who live here are no big deal in the grand scheme of things.
