Most, if not all would agree, that the sun is vital for human life to exist on earth. The sun with its solar system rotates around an arm of the Milky Way Galaxy composed of many stars, which in turn rotates around the centre of the Milky Way Galaxy composed of millions of stars. The Milky Way Galaxy
itself rotates around the local group of galaxies, which in turn probably rotate around a larger group. Perhaps this continues indefinately. It appears to mean that for life to exist on earth all these billions of heavenly bodies must exist as part of a great clock perhaps to infinity. If this is true, it is an awesome thought. The cost of our existence is beyond calculation. Is this true, using the facts of science alone ?
