Interesting fact:

Vast stone spheres were uncovered by banana plantation workers in Costa Rica in the 1930s, and they’re origins still puzzle historians to this day. They are dated back to the Diquis culture, who built them over the span of generations before the Spanish arrival in the region. Some of the spheres measure over six feet, and were damaged by the workers, who had heard rumors that the artifacts were filled with gold, and so made several attempts to crack them open like a Kinder surprise egg!
