They see the crescent,
we see the whole of the Moon.
Have you ever seen the whole of the Moon? Not a full moon, not the darkside of the Moon, the rest of the Moon. When there is a clear crescent showing you can sometimes see the rest of the Moon dimly. This is one of the most beautiful sights in the world, because it proves what kind of a Universe we live in. It is not the Universe of man at the centre, watched over by his man-shaped God.
The whole of the Moon is brought to you by the most amazing effect; the combination of starlight and EARTHSHINE. Light from stars hundreds of light-years away combines with light reflected from the Earth to gently illuminate the surface of the Moon, just enough for you to pick out the full circle clear against the black of infinity. I can never see it without producing a tear. Light from the sun has taken over eight minutes to reach us at the Earth, it is reflected off our continents, clouds and oceans to cross another quarter of a million miles of void to faintly illuminate the barren dust of our nearest neighbour, and then it retraces its path back another quarter of a million miles to our eyes. And it doesn't do it for us, it happened for billions of years before we ever saw it.
Where in all the Bibles and good books of the world is there a single concept to compare with that?
The theists' Universe is small and full of the stench of man. We atheists know that we are not the reason for the existence of the Universe. Our Universe has been there for many billions of years before we ever banged a couple of rocks together or talked to a man in the sky.
The Earth is less than a third of the age of the Universe. Man is much less than a thousandth of the age of the Earth.
Everywhere I look I see a greater Universe than any man-created God could ever conceive of. A Universe full of wonders.
God made it. That claim is not an answer to anything.
It is an insult to the Universe.
