Mysterious places can be found around the Earth, and, inexplicably, UFOs are often sited near these mystical areas. Planes and ships unaccountably disappear in the infamous Bermuda Triangle. Strange magnetic anomalies in Mexico's Zone of Silence have not only drawn missiles off their course, but seem to pull meteorites out of the sky.
Myths and legends have long been regarded as fantastic stories that describe powerful gods, mutant giants and fearsome monsters. But why do so many different cultures, separated by vast distances, tell the same stories? Is it possible that myths and legends were really eyewitness accounts of ancient astronauts descending to Earth?
Ancient underwater cities can be found around the globe, but could these aquatic worlds be the ruins of unknown civilizations - or even proof of extraterrestrial visitations? The infamous tale of the long lost city of Atlantis may be a preserved memory of an ancient alien metropolis.
If extraterrestrials influenced human history, can evidence of their existence be found in hidden tunnels and caverns around the world? Could a cave in Ecuador contain metallic books inscribed with secrets of alien technology? Was an ancient underground city in Turkey built with alien help... or as a refuge from an alien attack?
If ancient aliens visited Earth in the remote past, could they have given us advanced technology, past down through human history? And could this technology have helped the Third Reich build mysterious weapons and crafts far beyond the limits of 20th century science?
Super-heated death rays... High-tech rockets... Powerful sonic weapons... Are these examples of modern day science or could these technologies have originated thousands of years ago? Is it possible that early man possessed scientific knowledge far beyond that of our own century? Ancient texts, folklore and art suggest humans witnessed disc-shaped flying machines and fire-spewing chariots. Could these be accounts of flying saucers and rocket ships? And if so, was advanced technology left here by visitors from the stars? Did mankind's quest to unlock the secrets of levitation, anti-gravity and laser technology merely spring from our imaginations or did these ideas come from otherworldly beings?
Biblical texts and ancient lore frequently describe winged creatures carrying messages from the heavens. But are angels merely the product of mankind's imagination - or do they really exist? If so, where do they come from?
Various sites around the world; such as Göbekli Tepe in Turkey; the Incan ruins of Sacsayhuamán in Peru; the Carnac stones of France; and Zorats Karer in Armenia, show construction techniques and mathematical concepts that were not believed to have been known at the time, and that this knowledge was gained from alien visitors.
Aliens may have caused various disasters, as depicted in the Bible and other texts, or even tried to warn man of them; such as Noah of the Great Flood. Also proposed is that some disasters ushered changes in human evolution and that our leaps in technology over the centuries were achieved with alien help.
Extraterrestrials may have contacted various humans throughout history, such as Moses and Joan of Arc, to help guide and inspire them to achieve great things; or to pass on important messages for humanity; such as a supposed binary message given to a UFO-contactee during the 1980 Rendlesham Forest incident who believes it is the coordinates to a mythical island called Hy-Brazil.
