Longyou Caves: Created by a Lost Ancient Civilization with Machines?

Longyou caves, dated to be at least 2,000 years old, are one of the most mysterious ancient sites in the world. There were no historical records until Chinese farmers discovered them in 1992.

There are numerous questions about these caves and no one has been able to answer. Who built the Longyou caves? What purpose did they serve? How did the builders achieve the super précised craftsmanship over 2000 years ago? The set up of these caves reveal an advanced engineering knowledge similar to today’s remote sensing technology. In this video I discuss my research on the oversized stairs and the intriguing tool marks that match modern machine marks, which leads to my conclusion that the Longyou Caves were created by a prehistory civilization with lost ancient machinery.
