Book classified by CIA for more than 50 years explained how the world was going to end

A book which was kept a US state secret for more than five decades has now been declassified by the CIA.

The works of Chan Thomas - which details a shocking conspiracy theory about the planet's supposedly impending demise - has now gone public nearly 60 years after he first penned it.

The late engineer, UFO researcher and self-proclaimed polymath is the author behind the infamous book titled The Adam and Eve Story.

Modern day conspiracy theorists have continued to pedal his beliefs long after his death in 1998, and now, the details of his concerning predictions have finally been laid bare.

The Central Intelligence Agency (CIA) put a stop to the book's publication in 1966, for reasons that remain unknown to this day.

It is thought that the intelligence service might have been concerned that Thomas' theories might have sparked mass panic or that he may have spilled the details of secret government research.

The CIA declassified parts of the book back in 2013, but kept the rest of the literature under wraps, until now.

Thomas, who was a former US Air Force employee according to the Daily Mail, shared his interpretations on the Book of Genesis, several pre-Biblical stories, and historical geological phenomena in his writing.

The first chapter is titled 'The Next Cataclysm' and begins by saying: "Like Noah's 6,500 years ago... Like Adam and Eve's 11,500 years ago... This, too will come to pass..."

Essentially, Thomas believed that the world is rocked by a major disaster every 6,500 years, the damage of which is similar in scope to that of the 'Biblical Great Flood'.

Although Noah's Ark would have came long before us lot were born, experts aren't exactly sure on which date he supposedly had to cram animals two by two on his vessel to escape the deluge.

But Thomas insisted that his calculations were correct, using archaeological and geological evidence to support his timeline.

If the American was as good at maths as he claimed to be, that would suggest that the world ought to be bracing itself for another disaster of epic proportions in another 1,000 plus years or so.

Thomas' pole prediction

According to Thomas, these cataclysmic events are brought on by the Earth's poles - the two points where the planet's axis of rotation meets the surface - switching places, which is known as geomagnetic reversal.

Scientists say that this swap, which the author believed was responsible for earthquakes, tsunamis and severe weather which could wipe out the world, last occurred about 780,000 years ago.

"During a pole reversal, the magnetic field weakens, but it doesn’t completely disappear," according to NASA. "The magnetosphere, together with Earth’s atmosphere, continue protecting Earth from cosmic rays and charged solar particles, though there may be a small amount of particulate radiation that makes it down to Earth’s surface.

"The magnetic field becomes jumbled, and multiple magnetic poles can emerge in unexpected places."

In the The Adam and Eve Story, Thomas claims that this pole switch will ultimately be the downfall of human civilisation and spell the end of the world.

Thomas alleged that the Earth's magnetic field - which is constantly shifting and occasionally reverses polarity - will be shunted, causing chaos for the Earth as we know it.

He kicked off the first chapter with a chilling warning about what was to come (CIA)

In one chilling passage, he wrote: "In California, the mountains shake like ferns in a breeze; the mighty Pacific rears back and piles up into a mountain of water more than two miles high, then starts its race eastward.

"In a fraction of a day all vestiges of civilisation are gone, and the great cities - Los Angeles, San Francisco, Chicago, Dallas, New York - are nothing but legends.

"Barely a stone is left where millions walked just a few hours before."

He goes onto describe apocalyptic scenes taking hold of America's tourist hotspots, with winds 'with the force of a thousand armies' wreaking havoc with 'supersonic bombardment'.

Thomas then claimed that a tsunami stirred up in the Pacific would drown LA and San Francisco 'as if they were but grains of sand'.

He believed that 'within three hours', the entirety of the North American continent would be engulfed by devastation, as an earthquake will also supposedly allow huge cracks to form in the ground and magma to flow out.

But the other six large landmasses on Earth won't escape the wrath of the alleged cataclysm, either - as Thomas warned that each continent would also be annihilated.

He believed that they will all experience slightly differing versions of the same tragic end - with the 'horrendous rampage' only ceasing after seven days.

A new world

However, Thomas believes that the planet would be a lot different on the other side of things.

He wrote: "The Bay of Bengal basin, just east of India, is now at the North Pole. The Pacific Ocean, just west of Peru, is at the South Pole."

Thomas said that Greenland and Antarctica were hurled toward the equators, only to 'find their ice caps dissolving madly in the tropical heat'.

Let's hope that he wasn't as nifty with numbers as he thought then, eh?

According to Martin Mlynczak, a senior research scientist at the NASA Langley Research Center, we haven't got anything to worry about.

"It's just unfortunate that these things are being put out there," he told The Verge. "Extraordinary claims require extraordinary proof.

"And there's no proof and no science and no physics behind any of the claims about the magnetic field change being associated with climate change."

He dubbed Thomas' theory that the Earth's magnetic field will make a 90-degree switch as 'totally bogus'.

"If that's what happened every 6,500 years, we would certainly see it; it would be in all the records," Mlynczak added.

"The amount of energy to bring that about is tremendous. And you know, there's nothing to initiate it."

A NASA blog written by Alan Buis, who works in the space agency's Jet Propulsion Laboratory, also explains: "There’s no evidence that Earth’s climate has been significantly impacted by the last three magnetic field excursions, nor by any excursion event within at least the last 2.8 million years."
