有沒有可能在數千年前智慧生命已經訪問過地球，帶來了他們的科技，徹底的改變了人類歷史發展進程？
　　由Erich von Daniken撰寫，1968年出版的暢銷書《諸神的戰車》提出了一個“遠古外星人”的理論，顛覆了人們對于人類進程的信念。遠古洞穴壁畫中奇異的生物，秘魯的飛機跑道遺跡，和印第安文字中所描述的“神的飛行器”這些反常的考古文物只是一小部分被von Daniken引用作為遠古外星宇航員早已被我們的祖先所熟知的例證。
　　本片由von Daniken自己獨立制作，《遠古外星人》開始了全新的探險，尋找并評估這些證據。專注于最近30年間的最新發現，包括人類進化中不尋常的DNA和從埃及到敘利亞，到南美洲的最新解密的藝術品。這是對于一個從很多方面來說不能全信，但又不能被忽視的理論的一場沒有偏向的調查。
　　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.
