Who created the Nazca Lines—and why can they only be seen from the sky? For nearly a century, the mysterious geoglyphs of Peru's Nazca Desert have puzzled archaeologists, historians, and researchers around the world. Stretching across hundreds of square miles, these enormous figures depict animals, geometric patterns, humanoid beings, and perfectly straight lines that can only be fully appreciated from high above the Earth. In this episode of Ancient Aliens, investigators explore one of history's greatest mysteries. Were the Nazca Lines astronomical markers, sacred pathways, mathematical diagrams, or messages intended for beings in the sky? Why did the Nazca people create figures hundreds of feet long without the benefit of aircraft? And what explains the strange magnetic anomalies, mysterious elongated skulls, and legends connecting Nazca to ancient gods such as Viracocha? The investigation expands beyond Peru to explore giant earthworks, geoglyphs, crop circles, Serpent Mound, Tiwanaku, and other ancient sites that some researchers believe may be part of a global network of symbols designed to communicate across vast distances—or perhaps even beyond Earth itself. See all this and more in Season 9, Episode 12, "Beyond Nazca."
