In ancient times there are stories of the gods who appeared on Earth and brought knowledge and civilization to mankind. The oldest stories were from ancient Sumer and these gods were called the Anunnaki, or Nephilim, also known as the Fallen Ones. They were considered fallen after co-mingling with the daughters of men, so their realm became the Earth rather than the "heaven" from which they came. Their offspring were said to be giants and these myths and legends are found throughout the world. The author spent years of study to reveal an accurate, chronological history of these ancient beings, unveiling in this book a calendar of their events more accurate than anything previously known. This book presents vast research on worldwide myths, records of earth changes documented from cultures worldwide, and the author's immense work on planetary cycles to predict the return of these fallen ones, and the chaos and catastrophe that always came with them. The author was in a situation that, for many years, left him alone to study these things more completely than most anyone could imagine. As a result, the information being shared in this book should be studied seriously by those interested in these subjects. It is considered a masterpiece of investigation filled with new finds, new concepts and a totally new understanding of human antiquity.
