有没有大概在数千年前聪明生命已经访问过地球，带来了他们的科技，彻底的改变了人类汗青生长进程？
　　由Erich von Daniken撰写，1968年出书的脱销书《诸神的战车》提出了一个“太古外星人”的理论，颠覆了人们对付人类进程的信心。太古洞穴壁画中奇特的生物，秘鲁的飞机跑道遗迹，和印第安笔墨中所形貌的“神的飞行器”这些变态的考古文物只是一小部分被von Daniken引用作为太古外星宇航员早已被我们的先人所熟知的例证。
　　本片由von Daniken本身独立制作，《太古外星人》开始了全新的探险，探求并评估这些证据。专注于近来30年间的最新发明，包罗人类进化中不平常的DNA和从埃及到叙利亚，到南美洲的最新解密的艺术品。这是对付一个从很多方面来说不能全信，但又不能被忽视的理论的一场没有方向的观察。
　　Is it possible that intelligent life forms visited Earth thousands of years ago, bringing with them technology that drastically affected the course of history and man's own development?
　　Presented in the 1968 bestselling book Chariots of the Gods by Erich von Daniken, the theory of "ancient aliens" rocked people's beliefs in mankind's progress. Ancient cave drawings of strange creatures, remains of landing strips in Peru, and Indian texts that describe the "flying machines of the gods" were just a few of the odd archaeological artifacts cited by von Daniken as proof that ancient astronauts were well known to our ancestors.
　　Produced with the exclusive cooperation of von Daniken himself, Ancient Aliens launches all-new expeditions to seek out and evaluate this evidence, with a concentration on the latest discoveries of the last 30 years, including unusual DNA findings on man's evolution and newly decoded artifacts from Egypt to Syria to South America. It is a balanced investigation into a theory some believe cannot be true, but many agree cannot be ignored.
