TV Ancient Aliens - Season 4 Episode 6 : The Mystery of Puma Punku Ancient Aliens - Season 4 Episode 6 : The Mystery of Puma Punku 7/10 by 287 users At nearly 14,000 years old, the ruins of Puma Punku are the oldest and most baffling on the face of the Earth. No one knows who designed and built this complex of sophisticated inter-locking blocks, and then vanished. Researchers investigate the ruins on-location in Peru and present new computer analyses. Forensic evidence on the ground, together with local myths and legends, suggest this site may have been designed and even once inhabited by a species of extraterrestrials.
