What is the evidence of the lost continent of Atlantis, and who were the Atlanteans? Researcher and author of the book The Empires of Atlantis, Marco Vigato shares his insights from 15 years of research into the esoteric and archaeological evidence of Atlantis. He suggests that the fall of Atlantis thousands of years ago was due to the advance of materialism and the loss of spiritual science, but that the remnants of Atlantean knowledge were preserved in the human civilizations that grew out of their advanced culture, including the building of the pyramids at Giza.
