 We have often explored the many curious tales of a particular ancient global catastrophe, the Great Flood, a global deluge featured in countless ancient accounts. Yet additionally, we have also recently explored the compelling evidential corroboration to these ancient claims, supportive geological and scientific evidence, which intriguingly support their indeed once-being-such-a-flood, one of biblical proportions. The geological data supporting the change in sea levels are deserts, once-sea beds, submerged pyramids, ruins, and not to mention the tales of Atlantis. However, one area which is rarely, if ever mentioned in these same libraries of history, are the underground cities once built. All of them, found on nearly every continent, were each buried beneath the Earth in such a way as to avoid the land itself. The largest of these, Derinkuyu, discovered by a complete accident during a house renovation. It strongly suggests that many more may still be laying undiscovered, waiting to see light again, resting undisturbed in complete darkness for unknown millennia. Thousands of connected tunnels have already been found and explored all over Europe, thousands of miles of interlinking underground tunneling systems. All built as if those who created them found ground level either inhospitable or of a mortally perilous place to dwell, this for some unknown reason. Derinkuyu, as mentioned, a site we have explored in-depth before, not only has curious, multi-ton rolling door stoppers located at strategic locations, stone's modern man is incapable of moving. But was also reportedly lit by a natural gas pocket they tapped, tunneled a pipe through the complex with holes positioned along which, said a light as if a London Victorian street, ingenious if true, regardless of the genius that went into Derinkuyu itself. Modern corpses found within remains of the Hypogeum in Malta, it must be noted along with 7,000 other headless corpses, yet these complete bodies lay there alongside them. The oracle room within, just like the rumors of the natural light technology of Derinkuyu, also possessed, yet still possesses its own extraordinary example of ancient high technology. With an altar stone in the oracle room, placed in such a location, complemented by extraordinarily perfect architectural design, amplifies one's voice incredibly well and throughout the structure. Thousands of kilometers of groundwater-flooded caveways have recently been found in Belize, Honduras, El Salvador, along with many other locations, littered ancient ruins, remains and inhabitations. Once this flooding is dated, we believe it will push the currently held chronology of man and indeed these groups age back massively, a subject we will cover soon. However, these digressions merely scratch the surface of what we intend to explore further and indeed share with all of you. So, any support in this quest is greatly appreciated. To help us out, check the description for links. Why did ancient man seemingly hide underground? Why did they make such gargantuan efforts to dig, design, and then seemingly live in these places long term? These are questions we find highly compelling.
