Ancient Aliens (Seasons 1–22)

Watch Ancient Aliens (2010) online on iFILM — a History Channel documentary series now running more than twenty seasons, each episode examining a historical site, artifact, or ancient text through one persistent lens: could extraterrestrial visitors have played a part?

The series draws heavily on Erich von Däniken's 1968 book Chariots of the Gods, then layers on new cases. Helmet-like figures in Saharan cave paintings. The geometric lines cut into the Nazca plateau. Sanskrit references to flying craft called vimanas. Giorgio Tsoukalos and David Childress appear throughout, connecting evidence across cultures and continents.

Ancient Aliens does not deliver conclusions — it stacks questions. That is either a flaw or the point, depending on what you are looking for. For viewers who enjoy history presented as an open case rather than a closed textbook, the series holds up across dozens of episodes. Stream all seasons of Ancient Aliens online on iFILM.
