In Costa Rica, giant balls made of stone have become a pretty common sight. Now this one has been peculiar had they been simply boulders but these stone balls appear to have been chiseled and smoothed out. It’s something that nature alone can’t have created. However, no one knows who or what exactly made these stone spheres and apart from that, some of them stand taller than a fully grown person and weighs several tons which makes everyone question how these weird rocks were transported considering there aren’t any quarry or heavy machinery around areas where the balls can be found. Not that it would matter anyway since the stones the balls are made out of have been discovered to be volcanic rock meaning they couldn’t have come from any quarry at all.
