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

The Real Theories

A few scientists have constructed a world map that suggests that these stones were meeting points for humans traveling along a very specific path that is currently blocked by volcanic activity. These stones, theoretically, built a road map of both southern Europe and South America that pointed travelers to civilizations and safe spaces nearby. This is entirely plausible, yet impossible to prove, and it doesn't really seem like our Bosnian stone served that purpose at all.
