The Stone Spheres

In the past, lived several stone carvers in the Diquis Delta of Costa Rica who carved out hundreds of huge stone spheres that are considered to be the most amazing works of craftsmanship. These stone spheres are nearly perfect in shape. These mystical spheres are related to the Isthmo-Colombian region which is believed to be carved out from granodiorite (a type of igneous rock found in that particular region). Some of these spheres weights as much as 16 tons and are over 2 meters in diameter. When researched further the placing of these stones were found to be leading the tribe’s house location. Today, several of these stones could be found in private gardens of rich people and due to that reason, it becomes very difficult for the researchers to gather any new information about these sphere stones. What do you think they were used for?
