Series Six digs deeper into what role aliens may have played in shaping our world. Explore whether lost islands and mysterious, Eden-like paradises were actually earthly homes for aliens, and find out why the Greeks, Macedonians and other ancients believed the world's mountains to be sacred homes to all-powerful gods. This 'Ancient Aliens' collection connects science with faith and investigates the creatures of early religious texts including the scorpion-tailed locust in Revelations, Ezekiel's fiery, angel-driven chariots and India's half-human half-reptile gods called Nagas. The voyage travels down the paths of extraterrestrial seduction, Nazi time travel and the mysterious megalithic stone structures which continue to baffle archaeologists. History reaches back in to questions of where we come from, who we are and what else is out there.
