UFOs on the Moon: Truth Exposed, documentary: Interesting research about the hollow moon as an alien base.
Science now recognizes that the Moon is far older than previously thought, potentially even older than the Earth or the Sun. Our Moon is the only moon in the solar system with a fixed, nearly perfect circular orbit; it is not a solid object. Stories from the past explain how the Moon came to be in orbit. Why are there mysterious geometric structures on the Moon’s surface that resemble those in prehistoric Egypt and other parts of Earth? How is it possible that the Moon perfectly eclipses our Sun by miraculous chance? It is mathematically impossible for a total eclipse to occur on Earth if the Sun and Moon aren’t properly aligned.
