Trevoro Grassi is an independent researcher, studying prehistoric evidence of advanced civilizations, with a focus on the Great Pyramids, Sphinx, and the underground of Giza. I've been to over a dozen countries and visited over a hundred different pyramids, temples and sacred sites. I study megalithic stonework, mythology, astrology, math and geometry of ancient cultures in an attempt to reconstruct 'sacred sciences' of the last Golden Age. I've written a book series which is soon to be published and am currently working on a long format documentary series with Bill Brown, called 'The Secret Underworld Of Giza'.William (Bill) Brown is a retired civil engineer turned Gizatologist, who has spent the last 20 years investigating the mysteries of the Giza Plateau. He has been deep underground at Giza many times and in many locations. Bill has also carried out ground penetrating radar scans at many sites at Giza as well as at the Hawara Labyrinth site in the Fayoum Oasis. He has made many discoveries at both sites and is currently leading a project attempting to excavate and access many underground chambers and tunnels at Giza with the IRGE (International Research Group, Egypt) and Mission Pharaoh, an international collection of foundations supporting his work. https://www.youtube.com/watch?v=O6o77G5Najg&t=3287sTrevor Grassi: eltaearth@gmail.comBecome a supporter of this podcast: https://www.spreaker.com/podcast/earth-ancients--2790919/support.
