If ancient aliens visited Earth, what was their mission, and is there evidence that points to when they will return? Ancient Sumerian tablets describe an alien race, known as the Anunnaki, who came to Earth to mine for gold. Egyptian hieroglyphs depict hybrid creatures that were part man, part animal. Mysterious crop circles and unexplainable crystal skulls are thought to contain messages that man has yet to decipher. Strange evidence may exist in multiple cultures throughout history suggesting that aliens came here to explore, excavate raw materials, experiment on human beings, and even for pure conquest.

Nostradamus, regarded as the most well-known prophet in the history, wasn t alone. Edgar Cayce, America s most famous psychic, predicted the 1929 stock market crash and the coming of World War II. Joseph Smith, the founder of the Mormon religion, claimed to receive messages directly from God foretelling terrors of a corrupted government and an impending bloody civil war. St. Malachy predicted that the next pope would signal a time of great tribulation and ultimately, the end of the world. Isaac Newton determined when the horrors depicted in the Book of Revelations would come to pass. Web Bot, a computer program, predicted global catastrophes such as September 11. Web Bot s data is warning of the end of world around December 2012. Hugh Vail is prepping his family for apocalyptic scenarios and helping others through the American Preppers Network.

Centuries ago the prophet Nostradamus had visions of the end of our modern world. Now, scholars decipher his mysterious predictions and learn of terrible tragedies and catastrophic events that threaten to annihilate global populations. Nostradamus has successfully predicted the rise of Hitler, the assassination of John F. Kennedy, the detonation of the atomic bomb, and countless other events. Many fear that the remaining unfulfilled prophecies of Nostradamus will manifest before our very eyes. At Radius Engineering in Texas, Walton McCarthy shows state of the art underground shelters to a concerned family and in South Florida, Billy Carson of Fort Terra Nova meets with a prospective client interested in joining an underground shelter community large enough to house over 350 people.

Is the historical portrayal of the attack on Pearl Harbor as seen in movies accurate? Dr. Donald Goldstein, co-author of the best-seller At Dawn We Slept, leads a team of producers on a site survey of Pearl Harbor to revisit the attack and the lucky shot that sunk the USS Arizona on December 7, 1941. Weaving together interviews with survivors who share their stories from that fateful day and computer animation, the Pearl Harbor attack is re-created, as one of the most significant and traumatic events in American history is revealed as it's never been seen before.

Scientists at the University of Kansas believe gamma ray bursts were responsible for a great mass extinction on Earth 450 million years ago. The gamma rays strip away the ozone layer and generate chemical smog, producing a widespread chill that grips the Earth. It would cause food chains to collapse resulting in a prolonged worldwide famine. Also, an expected electromagnetic pulse will zap all of our electronics. Scientists predict the Earth will be able to support only 5 to 10 percent of its current population; that means close to 6 billion people will die--most by starvation. How will our modern cities hold up in the face of a previous global catastrophe?

In 79 AD Mt. Vesuvius destroyed Pompeii and killed 5,000 people. The volcano is quiet at the moment, but the only consistency in Vesuvius' eruptive history is a lack of consistency. The danger zone that surrounds the volcano includes the city of Naples and its one million residents; another two million people reside nearby. Scientists know that when Vesuvius erupts again they won't have much warning and another major metropolis will be destroyed.

The locust is one of the most destructive and dreaded life forms on Earth. American pioneers faced the largest swarm of locusts ever recorded. The 1,800 mile long and 110 mile wide cloud of insects ate their way through the heartland and blocked the sun for five days. Famine ensued, and thousands faced starvation. According to recent studies, the possibility of such a swarm returning to the United States is very likely. The destruction would be unimaginable.

65 million years ago a massive asteroid crashed into Mexico's Yucatan peninsula. 75% of all life on earth vanished; but could a single asteroid have been the lone killer? Theories about what happened after the impact have been speculated on by the entire scientific community. Ranging from global warming to lethal worldwide firestorms, ideas have been put forth--but none have been proven. Then in 1995 a new theory claimed that a powerful mega storm known as a Hypercane caused the extinction. The Hypercane allegedly reaches 20 miles into the stratosphere and has wind speeds of up to 700 miles per hour. 3-D computer animations will reveal how this storm could have brought down nearly all life on the planet.
