Pre-historic #China is home to some of the most incredible structures that hint at #advanced civilizations long before our current historical records begin.

Among these are the Yangshan #Quarry, the Longyou Caves, and the numerous #pyramids scattered throughout China, often shrouded in #mystery and suggesting a legacy of #pre-flood #megastructures.

All of these #ancient sites and #megalithic structures have some kind of machine marks that suggest they were built by an advanced civilization lost to #history.
