In this episode of A&E's Ancient Mysteries narrated by Leonard Nimoy, modern archaeologists investigate the strange phenomenon of UFOs by delving into the past as far back as the stone age. Many ancient civilizations erected monuments to the heavens with precision bordering on technological genius and often refer in their writings to bizarre flying objects seen in the sky. How were these civilizations so advanced that their technology is still unmatched in our contemporary society, and how are we to interpret these ancient references that share a startling similarity to UFOs being spotted today? Raising questions about the existence of UFOs, the identity of their occupants, and their possible influence on the history of mankind, this documentary examines clues from ancient civilizations that believed their societies originated with beings from above.
