Is Bigfoot simply an undiscovered species—or could the legendary creature have an extraterrestrial origin? In this episode of Ancient Aliens, investigate one of the world's most enduring mysteries through eyewitness accounts, ancient mythology, and controversial theories.

Journey from the Himalayas and the Pacific Northwest to the caves of Oregon and the ancient cities of Mesopotamia as researchers examine mysterious footprints, unexplained encounters, Native American traditions, the Epic of Gilgamesh, the Nephilim, and the Anunnaki. Along the way, they explore reports linking Bigfoot to UFO sightings, underground tunnel systems, and ancient accounts of giant, human-like beings found in cultures around the world.

Could Bigfoot be the product of alien genetic engineering—or might the legendary creature hold the key to humanity's own mysterious origins?
