有没有可能在数千年前智慧生命已经访问过地球，带来了他们的科技，彻底的改变了人类历史发展进程？
由Erich von Daniken撰写，1968年出版的畅销书《诸神的战车》提出了一个“远古外星人”的理论，颠覆了人们对于人类进程的信念。远古洞穴壁画中奇异的生物，秘鲁的飞机跑道遗迹，和印第安文字中所描述的“神的飞行器”这些反常的考古文物只是一小部分被von Daniken引用作为远古外星宇航员早已被我们的祖先所熟知的例证。
本片由von Daniken自己独立制作，《远古外星人》开始了全新的探险，寻找并评估这些证据。专注于最近30年间的最新发现，包括人类进化中不寻常的DNA和从埃及到叙利亚，到南美洲的最新解密的艺术品。这是对于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偏向的调查。
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.
