Stone spheres of Costa Rica

Okay kiddo, have you ever played with marbles? The stone spheres of Costa Rica are like really big marbles!

A long, long time ago, around 2000 years ago, people who lived in Costa Rica made these big spheres out of different types of rock. Some of them are big enough for a grown-up to stand beside, while others are small enough to hold in your hand.

Now, nobody knows exactly why they made these spheres. Maybe they were used for decoration or for special ceremonies. Some people even think that they might have been used as a map or a calendar!

These stone spheres are really special because nobody knows exactly how they were made. The people who made them didn't have the fancy tools we have today, so they might have used hammers and chisels to shape the rock into a round shape. They might have even used other stones to rub and polish them until they were smooth and shiny.

Today, these stone spheres are like a treasure for Costa Rica! They're so special that lots of people come from all over the world to see them. There are even some that are so big and heavy that they can't be moved! They're still there, in the same spot as when they were made all those years ago.
