Here are some that made it on the list.  The Rosetta Stone has been made extremely famous by the software and learning company but what about these others?

Rosetta Stone

Diquis Spheres

The Grauballe Man

Desert Kites

Atlantis

Acambaro Figures

Antikythera Mechanism

Rapa Nui

We hope you like the video and are inspired.  By the way a commen notion in regards to some of these enormous stones that have been found is that ancient civilizations knew how to soften materials and form them into stone.  I’m not sure if that is rumor or has any merit.
