Hidden Pyramids (S09E10)

Advances in infrared satellite technology are unveiling hidden pyramids beneath the Egyptian sands, while airborne laser scanning is revealing ancient structures concealed under the jungles of Central America. This has sparked a belief that we are on the cusp of a groundbreaking era of archaeological discovery. Recent findings suggest that Peru's ancient pyramids might predate those in Egypt, and a newly explored megalithic site in Indonesia is thought to be a step pyramid from a lost civilization dating back 20,000 years. Some ancient astronaut theorists propose that this global pyramid phenomenon indicates that early humans may have received assistance from extraterrestrial beings.
