Graham Hancock Says A Comet Destroyed Civilization 12,800 Years Ago.

Graham Hancock, author of 'Magicians of the Gods,' explains how a comet struck the earth some 12,800 years ago, wreaking devastation and all but wiping out human civilization. A select few, with knowledge of advanced technology, survived.

A huge comet enters the inner solar system about 30,000 years ago. It is captured by the sun, and it begins to go into an orbit that traverses the orbit of the Earth. It's subjected to all kinds of gravitational pulls. Comets are not as massively solid as asteroids. Comets are huge amounts of rock bound together with ice and what happens with these gravitational pulls and the passage of time is that this giant comet begins to break up into fragments, some of those fragments might be 20 miles across, others might be the size of your fist, and it begins to form a debris stream. Imagine a huge doughnut spread around the solar system. - Sure. - That's the debris stream of this comet and in it there's lots of small stuff which isn't dangerous and there's a lot of large stuff which is hideously dangerous. 12,800 years ago we are hit by about 8 large fragments of this comet with the epicenter of the cataclysm on the North American ice cap and continent wide wild fires across North America and the massive extinction of what are called the mega fauna, the large animal species of that, of that time. World climate changes, huge amounts of ice water from the ice cap have been released into the ocean. This interrupts the gulf stream and it causes a radical fall of world climate going into a deep freeze that will last 1,200 years. - Actually I believe Britain would be some of the first to go wouldn't it? One of the first to go if those oceans currents change you guys are going to freeze. - If we lose the gulf stream, oh yes, yes of course, of course, the gulf stream, many people don't realize what a huge role the oceans play in maintaining the stability of climate and if you interrupt these great conveyor belts that take warm water from the equator and bring it up into the cold northern latitude if you interrupt that then you don't just affect the Atlantic you affect the climate of the whole world. Now the mystery is that this episode which began 12,800 years ago ended equally suddenly 11,600 years ago and the answer to this mystery appears to be that more fragments of that comet hit the Earth that we crossed, we crossed the debris stream again 11,600 years ago, this time the impact were in oceans most likely the Pacific ocean, the biggest ocean on the planet. - Tsunamis? - Tsunamis, for sure, also a green house affect. Huge amounts of water vapor are thrown up into the upper atmosphere and this creates the perfect green house conditions which then explains why the earth in a matter of generations undergoes a warming of more than 10 degrees centigrade and all of what's left of the ice caps just melt and you have huge flooding, this is 11,600 years ago. The point is I'm not a big fan of doom and gloom and cataclysmic scenarios but I think we need to be aware of our cosmic environment.
