The World's Largest Stone Sphere is Evidence of a Lost Ancient Civilization

Atlantis and Some Rocks 

Atlantis is a theoretical lost society of extremely sophisticated technology and culture that disappeared before history began getting recorded. Some individuals believe that these stone spheres are a result of this lost civilization's impact on the Earth. These stone balls could have potentially been religious or culturally significant objects of these theoretical people, but there is no quality evidence that suggests that any of these theories are true.
