'Las Bolas'...giant stone spheres...What's their reason?

[fey421]

Why the people of pre-Spanish colonisation Costa Rico decided to carve 300 giant balls of stone is as much a mystery today as it was when the balls were discovered. Some are as large as two metres in diameter.

Now dated to between 600 & 1000ad. Spanish settlers ensured the indigenous population's cultural heritage was wiped out.

Does anyone know if the stones had markings (i.e. symbols) om them?
Any ideas on why these spheres were made?

If we believe that giants did exist on earth, then all these huge structures don't seem so big, but "their size". There was an article on another forum years ago, called Root Races, that spoke about how this is evolutionary possible, based on the changes in atmosphere as the earth was forming. Why dinosaurs were able to be so big, etc, and that there were 'giant men' back then, that were intelligent. if you look at the article from a science point of view, being possible, alot of ancient history begins to makes sense.
