An Ancient Mystery from Costa Rica

The giant stone balls of Costa Rica are one of the
fascinating
most fascinated human artifacts. The balls made in

prehistoric times and are perfectly round. The stone
comes from local mountains. It’s likely that stone tools

were use to make the balls. The biggest ball is eight feet
across and it is weighed 16 tons.

Unfortunately, we may never be discovered the true

purpose of the stones since only a small number of
stones can be studied in context. Many of the stones were

removed from their original place.

Archaeologists are annoying about this situation.
They say that when artifacts are found by members of the

public, they must not be moved. Photos can take, but the
artifacts should not be pick up.
