We are consciousness incarnated in stardust... - Graham Hancock

Now we know that man is more than two million years old,' exlaimed Heyerdahl, 'it would be very strange if our ancestors lived like primitive food collectors for all that time until suddenly they started in the Nile valley, in Mesopotamia and even in the Indus valley, to build a civilization at peak level pretty much at the same time. And there's a question I ask that I never get an answer to. The tombs from the first kingdom of Sumer are full of beautiful ornaments and treasures made of gold, silver, platinum, and semi-precious stones — things you don't find in Mesopotamia. All you find there is mud and water — good for planting but not much else. How did they suddenly learn — in that one generation just about — where to go to find gold and all these other things? To do that they must have known the geography of wide areas, and that takes time. So there must have been something before.

The Sabians were allowed to build a new Temple of the Moon God, and to continue their religious rites, after the Arab General Ibn Ghanam conquered Harran in the seventh century AD. This in itself is a sign of most unusual favor, since Islamic armies normally offered "pagans" the choice of either conversion or death. Even more interesting, however, is the Sabians' encounter with the Abbasid Caliph Abu Jafar Abdullah al-Ma'mun, who passed through their city in AD 830 and reportedly quizzed them intensively on their religion.
Remembering the Sabian pilgrimages to Giza, it is reasonable to wonder whether there is any connection with the fact that in AD 820, a decade before he visited Harran, it was Ma'mun who tunnelled into the Great Pyramid and opened its previously hidden passageways and chambers. Indeed, it is through "Ma'mun's Hole" that visitors still enter the monument today. Described by Gibbon as "a prince of rare learning," it seems Ma'mun's investigation was prompted by information he'd received about the Great Pyramid, specifically that it contained: 'a secret chamber with maps and tables of the celestial and terrestrial spheres. Although they were said to have been made in the remote past, they were suppposed to be of great accuracy.

[The cosmic impact that started the Younger Dryas] marked the end of their story, and the end of an epoch, really. There's not a single Clovis point found anywhere in North America that's above that black mat. They're all in it or below it. And there's not a single mammoth skeleton anywhere in North America that's above it. A huge part of the die-off could have been as a direct result of the impacts themselves, but impacts and airbursts south of the ice cap, particularly as far south as New Mexico, would also have set off wildfires. There's overwhelming evidence that gigantic wildfires raged at the onset of the Younger Dryas — in fact, more soot has been found at the Younger Dryas Boundary than at the Cretaceous-Paleogene Boundary. We did the calculations and it looks like as much as 25 percent of the edible biomass and around 9 percent of the total biomass of the planet was on fire and destroyed within days or weeks of the YDB. So in many areas if the animals weren't killed outright they wouldn't have been able to forage enough food afterwards to survive. The grass would have burned up, leaves on trees were gone. ... And you know, the other thing is that when comet fragments come in they're traveling incredibly fast and they literally punch a hole in the atmosphere. They actually push the air aside and they bring in that super cold from space, and when they explode in the air that cold plume continues to the ground and you literally have things frozen in place if they were close enough to where the plume came down. It's possible they were fried and then frozen all within a matter of seconds.
