Hello Lloyd: You might want to consider some of the following in your thread.
5.5 G Heinsohn and the Evidence of Stratigraphy
- Heinsohn has made a very important contribution to the revisionist debate by focus[-]ing attention on the evidence of stratigraphy outside Egypt. Dayton had uncovered many examples in museums around the world where near identical ancient artefacts of very similar styles and manufacturing techniques were given dates which varied sometimes by as much as 1000-1500 years. Heinsohn, from an extensive study of archaeological reports from most of the better known sites across Asia Minor, showed how these anachronisms had arisen. At site after site, archaeologists had artificially increased the age of the lower strata by inserting, without supporting evidence, 'occupation gaps' of many centuries. They did this in order to meet the expectations of excessive antiquity among historians, who had used Biblically derived dates for Abraham (c. 2100), initially seen as broadly contemporary with the great Assyrian king Hammurabi. Using this elongated time frame, great empires of the past such as the Sumerians, Akkadians and Old Babylonians were invented by late 19th C and early 20th C scholars to fill the historical voids. The ancient Greek and Roman historians, not surprisingly, knew nothing of these ancient peoples. Sumerian, said Heinsohn, 'is the language of the well known Kassite/Chaldeans, whose literacy deserves its fame'.
- He showed that the Bronze Age started in China and Mesoamerica some 1500 years later than in the Near East and proposed this gap be largely closed by lowering the ages of the Mediterranean civilisations. He cited the Indus Valley where the early period civilisations, dated from Mesopotamian seals to c. 2400BC, sit right underneath the Buddhist strata of 7-6C [BC]. Seals from Mesopotamia are found in the Indus valley and in Mesopotamia there are seals from the Indus Valley. So the excavators have to say they have an occupation gap of some 1700 years. Thus some sites only about 30km apart have chronologies some 1500 years apart. But in the same strata, supposedly 1500 years apart, they frequently find the same pottery.
- ... Heinsohn ... argued persuasively for equating, among others, the Mittani with the Medes (as did Velikovsky) and the Empire Hittites with the Late Chaldeans. His excellent paper on the archaeology of Hazor (C&CR 1996:1) revealed some important anachronisms. For example, two cuneiform tablets written in Old-Babylonian Akkadian and two more written in the Akaddian of the Amarna era were found in the upper layers of the site. Heinsohn asks 'How did tablets from the early second millennium end up in a stratum reaching its peak in the period of the Persian Empire (550-330 BC)?'. The tablets were, of course, immediately labelled 'heirlooms' by their finders. But, as Heinsohn pointed out, it seems strange that the later Hazoreans kept tablets for over 1000yr as heirlooms from the MBA or LBA, yet were apparently incapable of producing any texts of their own. Also, a clay jar inscribed in 23C [BC] Old-Akkadian was found in the Hyksos layer c17C [BC]. Yes, you've guessed - this was explained as yet another boring old 'heirloom'....
- Emmett Sweeney, a contributor to many early Workshops, [has] had two revisionist books published; 'The Genesis of Israel and Egypt'  and 'The Pyramid Age' . The latter in particular contains much well argued evidence in favour of a much lower Egyptian chronology.... Although his conclusion that the three Giza pyramids were built c870-770BC have not found much support, the real value of his books lies in the very wide range of evidence he introduces in support of many of his proposed synchronisms.
- Concerning Charles Ginenthal's model, http://www.maverickscience.com/misinformation.pdf, ... in Pillars of the Past, ... eliminate[s] some 1500 years from ancient Near Eastern history, [which he] derives from Gunnar Heinsohn.... Heinsohn argued that the Sumerian civilization never existed as such, and should properly be identified with the Chaldean empire of the first millennium BC. Among other sensational claims advanced by Heinsohn are that Sargon I of Akkad is to be identified with Sargon II of Assyria; that Hammurabi is to be identified with Darius; and that the Mitanni and Median empires are one and the same. ... Emmet Sweeney [is] known for arguing that Abraham brought the first instruments of civilization to Egypt and that the pyramids were constructed in the first millennium BCE.
