Across the globe, there are remarkable ruins, statues and carvings that appear to connect diverse ancient civilizations to one another. Hindu idols have been found in South America. Druid structures have been uncovered in the United States. And Egyptian hieroglyphs are carved in rock walls in Australia. Was our world once more interconnected than we ever thought? And if so, do the shared legends of sky gods and visitors from space point to a planet-wide -- extraterrestrial connection?

Ancient Astronaut theorists have long proposed that Earth is an extraterrestrial laboratory. If so, does it extend beyond humans into the animal kingdom? Accounts of animalist gods can be found across the globe, including insectoid and reptilian deities that curiously mirror modern alien encounters. Might this point to a direct extraterrestrial tie to the strange creatures on our planet, from Bigfoot and Mothman--to the evolutionary oddities that defy natural development on Earth.

Across nearly every continent on Earth we can find similar remarkable stone structures of unexplainable engineering feats. Might the building of these megalithic sites have been directed by an extraterrestrial hand, as Ancient Astronaut theorists have long proposed? From the curious discoveries made at the Great Pyramid, at Teotihuacan and Stone Henge, new evidence may suggest that these structures are not only connected, but also part of a more profound--and powerful--network.

Humans are just scratching the surface when it comes to what we know about our ancestors from the distant past. Lost cities, ancient texts, mysterious carvings, and unexplained structures provide clues to a long-forgotten time that goes further back in history than we could have ever imagined. From Egypt to China and even Antarctica, Ancient Astronaut theorists propose that the deeper we dig, the closer we will come to proving an extraterrestrial influence on Earth's ancient inhabitants.

Thousands of UFO sightings are reported in the United States every year, and intriguingly many of them center around U.S. military operations. Might extraterrestrials have a special interest in the country's warfare capabilities? Recently, the United States government has officially acknowledged that it is investigating unidentified aerial phenomena. What secrets have been kept from the public--and even some U.S. Presidents? And what role does the public play in demanding answers to our questions about extraterrestrials?

With our latest technological advancements, humanity has entered a new era in the search for life outside of our planet. From the discovery of exoplanets and the exploration of the moon to plans for missions to Mars, could man's quest to understand the universe be built into our DNA? Across the globe, many cultures believe that their ancestors came from the stars. Orion, Sirius and Pleiades are all connected to origins stories for ancient cultures around the world. As scientists continue to explore outer space, are we on the verge of discovering not only alien life but the very extraterrestrials that came to Earth centuries ago?

From the furthest reaches of human history, our ancestors left curious carvings, geo-glyphs, and hieroglyphic messages for future generations to decipher. Is it possible that these mysterious inscriptions, enigmatic crop formations, and encoded sacred architecture signify communication with extraterrestrial visitors? And if so, just what are they trying to tell us?

Throughout the world, there are areas where strange activity, UFOs, bizarre orbs of light, and electromagnetic anomalies are regularly witnessed. Many of these sites correspond to locations where ancient civilizations chose to build and rebuild their most sacred architecture. Ancient Astronaut theorists propose these sites are remnants of a lost extraterrestrial electrical system--one erected to draw energy from the Earth, to fuel spaceships, and possibly even to open gateways into other worlds.

In nearly every generation, there are great minds that can predict the future, seers who possess extrasensory abilities, and visionaries that almost single-handedly push humanity forward into a new age. These great thinkers, including Nikola Tesla, Srinivasa Ramanujan, Steve Jobs and others, have credited their genius to outside inspiration. Could there be an otherworldly source of knowledge that they are tapping into--one that may be steering the course of human history?

Tens of thousands of individuals go missing every year and many are never found. But this is not a new phenomenon. Throughout history, ships and planes have mysteriously vanished mid-journey--and entire civilizations, communities, and tribes have seemingly disappeared from the face of the Earth without a trace. Might there be a connection between all these missing person cases--one possibly involving otherworldly portals and even extraterrestrial beings?

Since the start of the Space Race, humanity has been driven to leave Earth and explore the cosmos. Could there be more to the mission than the public is told? There have been long-standing rumors about the true source for the extraordinary technology that launched us to the moon, curious statements made by returning astronauts, and even impossible architecture allegedly found on the Moon and Mars. Might our space program already have evidence that intelligent life exists in the universe--and that we are not alone?

Across the globe, there are remarkable ruins, statues and carvings that appear to connect diverse ancient civilizations to one another. Hindu idols have been found in South America. Druid structures have been uncovered in the United States. And Egyptian hieroglyphs are carved in rock walls in Australia. Was our world once more interconnected than we ever thought? And if so, do the shared legends of sky gods and visitors from space point to a planet-wide -- extraterrestrial connection?

Throughout history, there have been stories of flying serpents and fire-breathing dragons that descended from the sky, cross-cultural tales of the star ancestors that jumpstarted civilization on Earth, and even ancient lore describing otherworldly beings that interacted with humans in the remote past. Many of these accounts curiously mirror reports of modern-day alien encounters. Could the legends of these strange visitors from the stars be more than mere mythology? And if so, are they the same extraterrestrial beings that are visiting us today?
