When archaeologists excavated ancient Sumerian cities over 150 years ago they made some of the most remarkable discoveries in the history of humanity. Many of the discoveries came in the shape of cuneiform tablets. Carved upon the tablets were tales of enormous giants who wore horned helmets. They lived in massive Ziggurat structures and navigated the skies with flying machines. The most astonishing thing about these writings is that they are not works of fiction, they are eye witness accounts.
