Ancient megalithic architecture is on display all over the world . . . Israel, Egypt, Malta, Sardinia, Crete, Scotland, Ireland, Spain, France, Peru and the well-known monuments at Stonehenge. But unknown to most people, America has its share of ancient structures that no one wants to acknowledge, nor take credit for. Enter the never-ending, worldwide adventures of L.A. Marzulli, a man who continually states that he’s “on the trail.” His new DVD in the On the Trail of the Nephilim series, Mathematical Mysteries of the Moundbuilders, presents convincing evidence that the ancients had an advanced mathematical understanding of trigonometry and unique knowledge of the heavens. The state of Ohio contains a series of mammoth structures that have become known as “mounds,” the Serpent Mound and Octagon Mound among them. Who moved millions of pounds of dirt to build these enormous mathematical mounds, an event that never appears in the recorded history of any civilization? What’s buried inside those massive hills? Could these be the burial places of the giants of the Old Testament, hybrids that appeared to have fled the Promised Land and settled in locations all over the world? Join Gary and our always-exciting guest on his latest adventure!
