Alien Beacons
For centuries, ancient monuments and mysterious markings, visible only from the sky, have captivated and puzzled researchers. The Nazca Lines in Peru, with their sprawling designs of animal shapes and a humanoid figure, stretch across miles of desert while Ohio's Serpent Mound and France's precisely arranged Carnac Stones exhibit an advanced knowledge of astronomy and geometry. Around the world, similar enigmas emerge from crop circles inscribed with complex codes to ley lines linking sacred sites along energy-rich pathways. Could these sites be more than just ancient wonders? Might they have been placed intentionally as navigational signposts for extraterrestrial visitors who once journeyed through Earth's skies?
