I have frequently posted a review that I did of the "Fingerprints
of the Gods" by Mr. Graham Hancock". In response to one time
that I posted this review, Mr. Charlie Moody
(email@example.com) replied to complain about
me being arrogant you-know-what for simply pointing out the
numerous factual errors and omissions on the part of Mr. Hancock
in his book. He complained about archaeologists also ignoring
any data that contradicted "conventional" theories about the origin
of the Sphinx in Egypt and the "Pyramid" of Cuicuilco, Mexico

As I have gone over in detail in previous post, the age of the Sphinx as claimed by West and Schoch is a matter of considerable debate between an archaeologist, a writer, and a paleontologist and other archaeologists and archaeological geologists. The interpretation of your so-called *authoritative geological evidence* is at best ambiguous and at worst incorrect. Your claim ignores numerous papers that present contrary interpretations of the data. Like Dr. West, Mr. Hancock, and Mr. Bavual, you ignore any scientific research that contradicts in your arguments instead of noting that the research exists and explaining what the flaws in their arguments are. (References are given in an appendix at the end of this post). >Apparently, specialists in MesoAmerican archaeology are >untroubled by the paradox of proclaiming an earthwork to >be 2000 years old...an earthwork partially covered by a lava >flow which geologists have determined to be 8000 years >old. This claim misrepresents the facts and consists of material incorrectly cited from primary sources. Anybody who took the time to go back to the original references concerning this archaeological site, the "Pyramid" of Cuicuilco, which lies on the southern edge of Mexico City, D.F., would find that archaeologists, not geologists, claimed that the sediments below the lava flow, not the lava flow, dated to 8000 BP (6050 BC). Because these claims were made before the invention of radiocarbon dating, archaeologists, Cummings (1923, 1933), estimated, but not dated, the age of sediments lying below the Xitli lava flows, but covering the base of the "pyramid," to be 8500 of 30,000 BP (6550 to 28,050 BC). Later, numerous radiocarbon dates clearly demonstrated that these sediments are only as old as 2200 BP (250 BC) at their base (Fergusson and Libby 1963). Furthermore, the Xitli lava flows had never been dated to 8000 BP (6050 BC). Formerly, the lava flow had been considered to be younger than 2400 BP (450 BC), but is now considered to date to about 1540 BP (410 AD)(Cordova et al. 1994, Libby 1955). Finally, radiocarbon dates and distinctive pottery from mounds associated with the "Pyramid" of Cuicuilco, and found buried beneath the Xitli lava flows by quarrying operations, date the initial construction of the "pyramid" to be between 2750 to 2550 BP (800 to 600 BC), later remodeling until about 2150 BP (200 BC), and total abandonment before 1800 BP (150 AD)(Cordova et al. 1994, Heizer and Bennyhoff 1958, 1972). Mr. Moody, Mr. Hancock, and Dr. Hapgood somehow all manage to miss numerous radiocarbon dates and pottery data that clearly show the "Pyramid" of Cuicuilco is at most as old as 2750 to 2550 BP (800 to 600 BC). Neither it nor the Xitli lava flows that partially cover it are anywhere near as old as 8000 BP (6050 BC). Origin of the 8000 BP date I could find absolutely no primary references that claim that the Xitli lava flows that surround the "Pyramid" of Cuicuilco are 8,000 years old. Even Hapgood (1966, pp. 201- 204), the likely source of this claim concedes that these lava flows are only about 2000 years old. The source of this claim is likely a garbled estimate, not date, made by Cummings (1933) prior to the development of radiocarbon dating. As Hapgood (1966) states: "Cummings made an estimate of the time required to accumulate the eighteen feet of sediment between the underside of the Pedrigal and the temple pavement. He estimated, first, the age of the Pedrigal lava flow at 2,000 years, and here came very close to the truth. Then he measured the thickness of the sediments that have accumulated on the top of the Pedrigal since it was formed, and used this as a measuring stick to estimate the time required to accumulate the sediments below. He came to an estimate of 6,500 years for the time required to accumulate these eighteen feet of sediments." Note: Pedrigal lava flow is an old name for Xitli lava flows. As later radiocarbon dates of Fergusson and Libby (1963) and Cordova et al. (1994) prove the age estimate made by Cummings for the estimated 8,500 BP age of the sediments covering the base of the "Pyramid" of Cuicuilco is completely wrong. The problem is that rivers do not deposit sediment in consistent annual increments. Instead long periods of nondeposition are interrupted by major floods or changes in base level that can cause several feet of sediment to accumulate at irregular intervals. Radiocarbon dates listed by Fergusson (1963) clearly show that the base of these sediments at a depth of 21.5 feet date to about 2200 BP (250 BC). Even Hapgood (1966, pp. 204) comes to this same conclusion, however reluctantly. There is a clear lack of any evidence for either the Xitli (Pedrigal) lava flows or the underlying pottery-bearing sediments being as old as 8000 BP (6050 BC). Thus, the claim that these lava flows are 8000 BP (6050 BC) consists of pure fiction unsupported by any evidence or primary source. Discussion To repeat Mr. Moody's complaint: >Apparently, specialists in MesoAmerican archaeology are >untroubled by the paradox of proclaiming an earthwork to >be 2000 years old...an earthwork partially covered by a lava >flow which geologists have determined to be 8000 years >old. The reason that specialists in MesoAmerican archaeology are untroubled by this paradox is because this paradox does not exit. It is a falsehood created by people who failed to make the effort to do an adequate literature review concerning the age of the Xitli lava flows and the "Pyramid" of Cuicuilco. What is troubling and revealing about these claims is that a basic review of the published literature, even Hapgood (1966, pp. 201-204) the likely source of this claim, reveals the claim that the Xitli lava flows are 8,000 years is patently false and numerous published radiocarbon dates to disprove it. Furthermore, the references that I have found, conclude that the "Pyramid" of Cuicuilco is not 2000 years old, but possibly as old as 2,750 to 2,550 years not including later additions. Since this paradox has absolutely no basis in fact, nothing exists to trouble archaeologists. -- Final Notes --- The term pyramid is in quotes because the "Pyramid" of Cuicuilco is not a true pyramid. Rather. it is a conical mound faced by a river boulder and basalt slab veneer. It is about 370 feet (110 meters) and diameter at its base and now is 60 feet (20 meters) high. It was originally much higher (Kelly 1982). A good introduction to the archaeology of Mexico is the book "Mexico From the Olmecs to the Aztecs" by Micheal D. Coe and published by Thames and Hudson.

In part its abstract reads"
"The Pedregal lavas are fresh, well-exposed basaltic flows erupted
from the Xitle scoria-and-cinder cone in the southwestern part of
the Basin of Mexico. These lavas cover an area of 70 km (super 2)
and were emplaced over pyramids and other buildings (e.g. Cuicuilco
and Copilco archaeological sites). ..."
"A new age of 1670+ or -35 years BP (AD 245-315) obtained on
charcoal samples collected just beneath the lavas is favored
for the Xitle eruption. These samples originated by ignition of
vegetation during the emplacement of hot scoriaceous tephra."

1. "..That the pyramid and nearby settlements were abandoned as
a direct consequence of the volcanic activity of Xitle."
2. "The new dates, obtained from material which clearly is
contemporaneous with the volcanic activity, suggest that the
eruption took place around 1670 years BP, some 300 years
later than previously thought."
