Who Built the Moon?

The authors of Civilization One return bringing new evidence about the Moon that will shake up our world. Christopher Knight and Alan Butler realized that the ancient system of geometry they presented in their earlier breakthrough study works as perfectly for the Moon as it does the Earth. On further investigation they found a consistent sequence of beautiful integer numbers when looking at every major aspect of the Moon--no such pattern emerges for any other planet or moon in the solar system. In addition Knight and Butler discovered that the Moon possesses few or no heavy metals and has no core--something that should not be possible. Their persuasive conclusion: if higher life only developed on Earth because the Moon is exactly what it is and where it is it becomes unreasonable to cling to the idea that the Moon is a natural object. The only question that remains is who built it?
