For centuries, ancient monuments and mysterious markings, visible only from the sky, have captivated and puzzled researchers.

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?
