Michael Tellinger, has estimated the number of ancient stone ruins to be 100,000 or possibly much higher. Some of these “stone circles” have no doors or entrances while most are connected by an expansive network of channels that are often misinterpreted as “roads” by some historians. This connected grid of circular ruins are immersed in a seemingly never-ending expanse of ancient agricultural terraces surrounding the structures. Adam’s Calendar is considered to be the most famous among these ruins.
