The ones with Egyptian/Masonic artefacts? Even more interesting things have been found in South America. The Atlantean survivors first surfaced there and became the Toltecs. They brought the remnants of their culture with them. Egypt was another survivor refuge and not the origin of any of it. The Great Pyramid was built before the cataclysm that destroyed the Atlantean civilization as a vault to preserve their knowledge against what they knew was coming. Like many other ancient megaliths, it was built to withstand severe earthquakes and floods. It had scientific information coded into its shape and dimensions. What we think is our past, whether the biblical version or the more scientific one that we crawled out of the ice age as ape-men and then rapidly developed from there is all Masonic BS. We've been around as intelligent, fully developed humans for millions of years.
