Anti diffusionists (those who discount the transoceanic seafaring abilities of bronze age mariners) act like Sergeant Schultz on Hogan’s Heros (“I see nuthink!”) when they are confronted with the overwhelming evidence that the ancient Olmec language of Central America bears close resemblance to Malinke Bambara, in the Vai dialect, of the Manding language group of western Africa, indicating that Central America was first settled by seafarers from the east, as confirmed in the ancient mexican book, the Popol Vu.
And when you consider that Atlan (the legendary mexican homeland) was Atlantis, west meets east, in legend and in reality (see category Atlantis Revealed), fitting the overwhelming evidence that the Manding language of west Africa, in the shadow of the Atlas mountains of Morocco, was the parent language of the Olmecs, who settled Central America circa 2000 B.C., developing from the Manding language into pre proto Mixe-Zoquean language, from which developed the Isthmian language script discovered on the Tuxtla Statue and the Mojarra Stela, the decipherment of which was enabled by the realization that the Manding language resembles the Mayan, and so, the linguists worked backwards to deduce the Isthmian. The pre proto Mixe-Zoquean was hypothesized by Terrence Kaufman, because some words are common in the many languages of the indigenous people of Central America, common words such as for cacao, incense, turkey, and tortilla, proving that they all derived from a common original language.
And the ancient Olmec language and mathematical knowledge was the source for the Mayan tuns, baktuns, and katuns, of days, base six enumerated, numbers derived from the ancient mapping method described in article #2 at http://IceAgeCivilizations.com, the method used to accurately measure and map the earth by its wobble rate, which enabled the ancient Atlanteans to navigate all over the globe, evidenced by the similarity of other languages to the Manding and Olmec, Sumerian, Elamite, and Dravidian, as documented by Clyde Winters through his decades of great work.
The mainstream archaeologists and anthropologists, who sneer at Winters’ work, and the work of Barry Fell of Harvard (the father of diffusionism), are obviously on the wrong side of this argument, which in fact corroborates the book of Genesis, with the Ice Age having ended circa 1500 B.C., when the Exodus occurred, when sea level rose to submerge hundreds of coastal stone and brick structures (see category Submerged Ancient Ruins), and the climate dried out drastically (see category Catastrophic Climate Change).
