Atlantis and Lemuria! The author, Dr. Heinrich Kruparz, a geologist, is personally familiar with many of the areas where these sunken cultures were located. To this day, their traces can be found: Mohenjo Daro, an atomically destroyed urban culture in the Indus Valley, or the stone sculptures on Easter Island, and much more. The author also weaves in insights gained from studies in related fields of knowledge, such as the construction of the Great Pyramid or myths from various peoples that state that humans and dinosaurs coexisted. These are insights that the reader has most likely never heard or read about, which provide evidence for the existence of the aforementioned lost continents. The author has traveled to many parts of the world for professional reasons, where he was able to gather relevant information.
