In the case of the Younger Dryas, the jeopardy that humanity faced was not from nuclear missiles but from the incoming fragments of a disintegrating giant comet, traveling at tens of kilometers per second, with the larger fragments as deadly as hundreds of nuclear warheads. Indeed, it is estimated that the total explosive power of the comet fragments that struck the earth in repeated episodes over a period of 21 years some 12,800 years ago would have been of the order of 10 million megatons — 1,000 times greater than all the nuclear devices stockpiled in the world today.

The entire pre-Columbian literature of Mexico, a vast library of tens of thousands of codices, was carefully and systematically destroyed by the priests and friars who followed in the wake of the conquistadors. In November 1530, for example, Bishop Juan de Zumárraga, who had shortly before been apointed 'Protector of the Indians' by the Spanish crown, proceeded to 'protect' his flock by burning at the stake a Mexican aristocrat, the lord of the city of Texcoco, whom he accused of having worshipped the rain god. In the city's marketplace Zumárraga 'had a pyramid formed of the documents of Aztec history, knowledge and literature, their paintings, manuscripts, and hieroglyphic writings, all of which he committed to the flames while the natives cried and prayed.'
More than 30 years later, the holocaust of documents was still under way. In July 1562, in the main square of Mani (just south of modern Merida in the Yucatan), Bishop Diego de Landa burned thousands of Maya codices, story paintings, and hieroglyphs inscribed on rolled-up deer skins. He boasted of destroying countless 'idols' and 'altars,' all of which he described as 'works of the devil, designed by the evil one to delude the Indians and to prevent them from accepting Christianity.' Noting that the Maya 'used certain characters or letters, which they wrote in their books about the antiquities and their sciences' he informs us: 'We found a great number of books in these letters, and since they contained nothing but superstitions and falsehoods of the devil we burned them all, which they took most grievously and which gave them great pain.

The view of Professor Robert Schoch Schoch is a renowned figure, indeed notorious, for the case he's made, based on strict geological evidence, that the Great Sphinx of Giza bears the unmistakable erosion patterns of thousands of years of heavy rainfall.6 This means it has to be much older than 2500 BC (the orthodox date, when Egypt received no more rain than it does today) and must originally have been carved around the end of the Ice Age when the Nile valley was subjected to a long period of intense precipitation.
