Civilization One : Watkins Publishing : 9781907486098 : 1907486097 : 08 Jul 2010 : How a quest to crack the mystery of the Megalithic Yard led to the discovery of compelling evidence pointing to the existence of a highly advanced culture predating the earliest known civilizations   There must have been a ?civilization one.? Knight and Butler reveal the secrets of an extraordinary, integrated measuring system which might have been lost to the world for ever. It was a system, far more advanced than anything used today, which forms the basis of both the Imperial and Metric measure systems. These ancient scientists understood the dimensions, motions and relationships of the Earth, Moon and Sun?they measured the solar system and even understood how the speed of light was integrated into the movements of our planet. Their conclusions fly in the face of everything that we thought we knew about the origins of the modern world?but the evidence is incontrovertible.
