Hi Blue Grass....Thanks for the clarification, and wow, that's a weird coincidence in terms of the title of the documentary and the theory you described ("a meteor hitting the ocean creating a tsunami that flooded the entire earth"), that certainly misled me to the wrong docu.
I haven't seen that "Search For Noah's Ark" program but I think I know now the theory you are referring to. I have encountered it in recent writing on the subject, and it is certainly less "woo" than the outlandish theory espoused by the "In Search of Noah's Ark" documentary. It is discussed in detail in the article "The Archaeology and Anthropology of Quaternary Period Cosmic Impact" by W. Bruce Masse published in the 2007 book Comet/Asteriod Impacts and Human Society.
I am of two minds about Masse's theory. He gives a good survey of recent Holocene impact craters and I myself have noted the suspected impact crater at Umm al Bini in southern Iraq (which would have been in shallow waters offshore in the third millennium BC) which, if a genuine impact crater, dates only to the Holocene period and which must have been formed prior to recorded history (unfortunately the conflict in Iraq has precluded on-site research). Such an impact could have quite plausibly created the kind of flooding attested archaeologically in southern Mesopotamian sites. I am much less satisfied with Masse's handling of mythological data. He takes a potpourri of flood and world destruction myths that contain elements that could be construed as reminiscent of asteroid/comet impacts and relates them all (or many of them) to a single hypothetical impact event (as opposed to, say, exploring what other kind of literary/narrative background there may be to such myths). The most speculative and unconvincing claim is his attempt to date the impact event to May 10, 2807 BC on the basis of selected astrological details in myths and literary texts that can only be tenuously and arbitrarily linked together as representing somehow a common tradition. This includes a prediction by a 9th century AD Arab astronomer on what the position of the planets would be on Judgment Day. I find it a real stretch to think this eschatological expectation, which isn't even explicitly about a primeval deluge, preserves a historical memory of the alignment of the planets on the eve of a hypothetical asteroid impact nearly four millennia earlier. Nor are planetary conjunctions a conspicous feature of most flood myths. And it strikes me as suspicious that the planetary conjunctions he mentions are those in Pisces and Aquaries, constellations that intrinsically pertain to water. It seems rather facile that he takes these at face value as reflecting a single historical planetary conjunction in the distant past when there is a more obvious explanation of why these constellations figure in certain flood myths and statements predicting a future flood or destruction of the world.
