History HD

History - fascinating and exclusive programs on subjects ranging from American and world history to explorations of major events in politics, entertainment and social history.

History

Across continents and cultures, remote caves, mountains, and subterranean labyrinths have long been regarded as secret refuges-hidden homes of gods, giants, and beings not entirely human. Australia's Black Mountains are steeped in tales of vanishing travelers and otherworldly guardians, while Native American legends link the Oregon Caves to Bigfoot-like creatures who retreat into underground sanctuaries; ancient Greek myths tell of troglodytes; sky-born beings said to dwell in caverns.

Ancient Aliens: Origins

Extraterrestrial Lairs

For decades, physics has probed the mysteries of time itself, testing the boundaries of what is truly possible.

Alien Time Travelers

The top destination for all things history.

Pythagoras was initiated into the cosmic language of geometry; the Knights Templar and Freemasons incorporated sacred numbers, mystical patterns and divine symbols into their art and architecture.

Alien Brotherhoods and Codes

From military-grade exoskeletons that grant superhuman strength to advances in visual spectrometers that enhance human perception, today's technologies are rapidly transforming myth into reality. Sonic weapons capable of toppling structures evoke the biblical fall of Jericho. Invisibility cloaks under development invoke the Ring of Gyges, said to render their wearer unseen and untouchable.

Alien Reinventions

Could the sacred encounters that shaped millennia of faith-and the warnings delivered by modern contactees-be part of the same phenomenon: misunderstood interactions with advanced beings from beyond our world?

Messengers Among Us

For centuries, humans have pondered a profound question: Are we alone in the universe?

Are We Alone?

Ancient accounts of monstrous creatures appear in cultures across the globe, today, sightings of Bigfoot, the Loch Ness Monster, and Reptilian beings continue, with their bizarre forms and behaviors eerily echoing ancient descriptions.

The Cryptid Mystery

Flood myths have endured across cultures for millennia, each retelling events said to have reshaped the Earth; in the Bible, Noah's flood symbolizes divine cleansing; a Sumerian legend tells of King Ziusudra and his survival through a great deluge.

Extraterrestrial Deluge

The Greek pantheon, the Anunnaki of Sumeria, and the Yellow Emperor of China were revered not just as deities but as powerful sky beings; could today's rulers still carry traces of extraterrestrial DNA, inherited from the so-called gods?

Otherworldly Rulers

Across the globe, sacred sites have long been viewed as gateways to the stars; might they serve as wormholes, intentionally designed to connect humanity with its ancient alien ancestors?

Gateways to the Stars

From elaborate ceremonies featuring garments strangely reminiscent of space suits to masked dancers with alien-like faces, human history is rich with traditions that seem to honor mysterious beings from the sky.

Extraterrestrial Rituals

Across time and cultures civilizations have preserved remarkably similar accounts of sky beings who bestowed the foundational elements of civilization, language, mathematics, architecture, medicine, and astronomy.
