Ancient Aliens - Season 6 Episode 9

Legends of lost and mysterious islands, advanced civilizations and Eden-like paradises have been told by sailors throughout human history. Is it possible these stories are more than just the myths of imaginative seafarers? Might evidence of our Ancient Alien origins be found by exploring the world's most remote islands--strategic spots where extraterrestrials may have once made their earthly homes... and possibly still visit today? Unidentified submersible objects going at lightning speed... strange crafts coming out of water near remote volcanic islands... and mystifying megalithic ruins in the middle of the ocean. Is it possible UFO activity could be hidden deep underwater and off the coasts of islands? Could this explain why so many islands around the world have stories of unexplained sightings of objects both overhead and beneath the sea going back centuries?
