Ancient Aliens, Season 8

In Season 8 of Ancient Aliens, the search for evidence of extraterrestrial intervention on Earth goes farther than ever before. Are the mysterious conditions found inside some crop formations – such as distinctive biophysical and biochemical changes in the grain structure of the affected crops – proof that some crop circles really are the work of aliens? Might ancient stories that give detailed descriptions of humanoid robots actually be historical accounts of advanced technology – proven true by the discovery of a 2,200-year-old computer? Ancient Astronaut theorists head out into the field to examine strange carvings found in southern India, meet with crop circle experts in England and visit a top Japanese robotics lab.
