Ancient Astronaut theorist, Giorgio Tsoukalos, shares his insight on massive stone structures and strange, giant figures known as Monoliths. What compelled ancient man to move colossal stones, in some cases weighing thousands of pounds, and to build remarkably similar stone monuments all around the world? From the jungles of Costa Rica to England's rural countryside, ancient people achieved extraordinary feats of construction without advanced tools or technology. Is it possible that extraterrestrials instructed the ancients to build these complex structures? Or were our ancestors driven to create these monoliths in order to reconnect with celestial travelers who once walked the Earth? Could ancient monoliths hold advanced, extraterrestrial powers we have yet to realize? And if so, just what will happen when we unlock the mystery of the monoliths?

Did our ancestors have an understanding of how to generate power thousands of years before modern man? Ancient Astronaut theorist, Giorgio Tsoukalos, theorizes that some of the most famous ruins on Earth may be long-forgotten power sources that hold a celestial connection. From the discovery of an ancient battery in Iraq and the depiction of a primitive light bulb in Egypt, to a wireless power grid that may have reached around the world, there is evidence suggesting ancient man had access to electricity, which, until recently, was believed to be a modern day phenomenon. But if our ancestors did possess power, where did they gain this knowledge? Is it possible that they received this wisdom from an extraterrestrial source as ancient astronaut theorists contend? And, if so, why did the power stop flowing?
