Reveals Zecharia Sitchin's groundbreaking research into the code left behind by the creators of humanity. • Explains how the Anunnaki were not merely the mythical gods of the Sumerians, but rather the founders of human life on Earth. • Using Biblical and ancient Sumerian sources, explains how to decode these messages our star ancestors left behind. Daring to challenge our long-held beliefs about the origins of man, Zecharia Sitchin suggests that humans are not the children of God, but rather the children of the Anunnaki, an ancient race from the planet Nibiru. His revolutionary theories are supported by his intense scrutiny of not only ancient Sumerian texts but also stone structures all over the world. The similarities and astrological significance of these formations suggests that rather than looking for guidance from leaders here on Earth, humanity should instead look to the sky for answers. The Earth Chronicles deal with the history and prehistory of Earth and humankind. Each book in the series is based upon information written on clay tablets by the ancient civilizations of the Near East. For the first time, the entire Earth Chronicles series is now available in a hardcover collector's edition.
