In the first half, author and researcher, Donald Zygutis joined Richard Syrett to discuss how Carl Sagan, when he was at Stanford University, produced a controversial paper funded by a NASA research grant that concluded ancient alien intervention may have sparked human civilization. Zygutis believes that when NASA saw the paper that Sagan produced in 1964, they suppressed and hid it away. He says that the paper speculates that extraterrestrials may have visited Earth thousands of times in the ancient history, and may have even "terraformed" the planet to make it habitable by humans. Zygutis added that Sagan was present at the very first scientific meeting discussing the search for ETs by radio signals, which later evolved into the Search For Extraterrestrial Intelligence (SETI.)

Sagan contracted a rare form of cancer when he was 60 years old and died two years later. Zygutis believes in the possibility that Sagan was targeted on orders from someone in the Pentagon. He said that this could have been accomplished with a "minuscule amount" of a radioactive substance. Soon after Sagan’s death, NASA announced a project to achieve interstellar travel in 100 years. Since they had previously claimed that this was impossible, Zygutis thinks that this would have made Sagan revive his ancient alien ideas in public since it would have admitted the possiblity that other civilizations could have done the same thing. He concluded that had he lived longer, Sagan "would have found the smoking gun" for definitive evidence of historical visits by non-humans.

In the second half, author Xaviant Haze revealed how giants were a dominant feature of native origin myths as well as extraordinary first-person tales by early explorers. He began by pointing out that Abraham Lincoln was "definitely a believer" in the idea that giants inhabited the ancient Americas. Haze says that there is evidence for a prehistoric giant race of humans throughout the oral traditions of many North American tribes, who regarded them with dread as cannibals. He described the first books published by the Smithsonian Institution on excavations where giant bones were uncovered in the ancient mound complexes of North America. By the 1880s though, Haze said that bones and other evidence would be shipped off to the Smithsonian, and that "without fail, that’s where the trail ends."

Some of the best reports on the ancient giant race were left by early European explorers. Haze read excerpts from the accounts of Ferdinand Magellan and Amerigo Vespucci, who described giant people in what are now the San Francisco Bay area and the island of Curacao. Haze has also found that oral tradition also attributes extensive copper mining in ancient America to the tall people, well before Europeans arrived on the continent. Haze lamented that some of the records of giant races have been obscured and tainted by an extensive history of hoaxing, especially in the latter part of the 19th century, but remarked that "science and academia should be opened" to reveal the true facts. Haze believes that the archaeological establishment is "admitting it by not admitting" that the evidence for giant races exists.
