#1 - The Forbidden Zones

#2 - Alien Wars
Season 8 - Episode 9 - Aired 10/2/2015
On March 19th, 2002, Gary McKinnon was arrested for hacking into 97 Pentagon and NASA computers over a 13-month period, in what authorities call the "biggest military computer hack of all time." McKinnon claimed that he found evidence of a secret American space fleet, by way of a list of dozens of "non-terrestrial officers" and their assigned spacecraft, replete with USSS (United States Space Ship) monikers. Might the United States military really have a secret space program? And if so, are we preparing for a space-based war with other nations... or other species? Ancient Astronaut theorists suggest that there are numerous factions of alien races with competing agendas visiting Earth, and that there is evidence they have been in conflict with each other for thousands of years. According to these theorists, there is evidence that these wars actually took place here on Earth in the distant past--not between gods, but between extraterrestrial visitors.
#3 - The Alien Agenda
Season 7 - Episode 12 - Aired 5/1/2015
Many of humanity's most significant turning points have bore witness to unexplainable events. Is this merely coincidence, or could it be evidence that the course of human history is being manipulated by an alien agenda? Ancient Astronaut theorists have long proposed that extraterrestrials played a pivotal role in our past, and some believe they continue to keep a careful watch over the progress of mankind. Even high-level government officials have made claims that extraterrestrials are visiting our planet with an interest in our technological advancements, including former Canadian Defense Minister Paul Hellyer, who stated that that the cosmos are teaming with life. Could the UFO phenomenon be real? Have extraterrestrials been monitoring human progress for thousands of years--at times helping us to advance, and at other times holding us back?

A man shrouded in mystery and intrigue, Tesla would speak about obtaining insights in a flash of genius, how he could visualize his inventions in full-detail and manipulate them in his mind, and his compulsion to invent the future. But he also claimed to have direct communication from intelligent beings on other planets. Is it possible that this alleged mad scientist, so far ahead of his time, was actually a human "receiver"?

#7 - The God Particle
Season 6 - Episode 17 - Aired 8/8/2014
It has been called the key to the universe and possibly the most important scientific breakthrough of all time. Could the so-called "God Particle" reveal the truth about our origins?

The age-old question, "where did we come from?" remains a mystery, but in 2012, scientists at CERN laboratory announced the discovery of the "God Particle"--the subatomic particle that is believed to give mass to matter--and offers a closer understanding of just how the universe began. The discovery seemingly pitted science against religion. But could science and religion actually be kindred spirits?

#8 - Alien Encounters
Season 6 - Episode 18 - Aired 8/15/2014
Stories of strange encounters accompany many of history's major events. Is it merely coincidence? Or might it be evidence of extraterrestrial intervention?

The Sumerian gods are said to have created mankind; the Hebrews believe God gave Moses man's first laws, the Ten Commandments, and the angel Gabriel reportedly shared divine wisdom with the prophet Muhammad. But is it possible that these supernatural visitations were not actually the work of the gods--but rather a race of extraterrestrials using advanced technology to create and shape our civilization?

And a ghostly image of George Washington was witnessed by hundreds of soldiers at Gettysburg–prompting an official government investigation.

Ancient emperors, kings, and pharaohs were often attributed with otherworldly strength, ability, and wisdom; many were even considered gods by the people they ruled. Who were these exceptional leaders, and how did some accomplish so much in their time? Ancient Astronaut theorists believe that these great rulers throughout history were "chosen" and guided by extraterrestrials. Is it possible that the world's legendary leaders might have shared a common genetic trait? A so-called, "leadership gene"?

Demonic seduction… hybrid offspring… and strange abductions. In cultures throughout the world, there are tales of intimate encounters with otherworldly beings. But could these stories be more than just mythology? Scientific deconstruction of human genetic makeup has revealed that our origins are not what we once believed. Biologists have determined that early humans mated with several other species of intelligent hominids. Neanderthals, Denisovans, and a third–as of yet unidentified–species may also be represented in our DNA. Is it possible that tales spanning from fallen angels to Greek gods, medieval incubus and succubus to today's extraterrestrial sexual encounters are all one in the same? And if so, is it all part of a greater agenda? Might examining these experiences provide not only evidence of extraterrestrial sexual intervention in the remote past, but also reveal the true nature of mankind's origins?

Scholars are divided as to who built them, and why. Some Ancient Astronaut theorists believe that the massive markings have an extraterrestrial connection, and perhaps the ancient people of the region created these gigantic figures in tribute to the gods who visited them. And with one of the largest deposits of nitrates in the world--a key ingredient in rocket fuel and weaponry--could Nazca have been a mining operation for advanced beings in the distant past?
