I presented this evidence more times than I can count and the author of these words simply ignores it.
But since it's on-topic and suits my needs I'll go through some of it again anyway and then in the next post I'll be told I'm running from the question.
The Mesopotamians said there existed a single language to "pray to the gods". Of course this is a mistranslation of something that actually meant "honoring scientific theory".
This concept also appears all through the Bible with the most remarkable being I Corinthians 14. There isa also, of course, Genesis which speaks of the language becoming confused.
But more importantly when the Pyramid Texts and Coffin Texts are solved simultaneously with reverse engineering the pyramid a new form of language can be seen that I call Ancient Language.
At some indeterminate point (circa 2000 BC) there were no longer enough individuals who spoke AL to operate the state. Even Merer in 2700 BC apparently did not speak Ancient Language and he had a very important position as the operator of what was apparently a "tug boat". AL language speakers after the change in language/ collapse of the tower of babel were apparently called "Nephilim" and many are listed in the Bible. So we have a language that explains how superstitious Homo Omnisciencis could survive to invent agriculture and cities. The existence of this language explains how I debunked ramps and showed the horizontal and vertical lines that disclose the pyramids were built by pulling stones up one step at a time. It explains w2hy the Bible and Sumerians both said there was one language and then "confused" people came about. It explains the origin of not only vocabulary including most of the ancient words but most modern words as well. It explains how anyone could predict the results of the infrared scan. AL explains not only most of history but gives details about pre-history as well. It explains how it's possible that writing was invented in 3200 BC but history didn't start until ~2000 BC (the official introduction of modern language).
But it goes far beyond just this. It shows why science doesn't even have a working definition for "consciousness". It shows that the basis of life is individual consciousness (the only kind in existence) and not survival of the fittest.
Dates in the distant past are unknown. I have to with the dates that Egyptology made up as these underlie all of archaeology even though they have been scientifically shown to be wrong. Using science I estimate the change in language to be around 2000 BC but it's difficult to give a margin of error. It was probably between 2100 BC and 1850 BC and then some Nephilim survived as late as ~ 1200 BC. But these are mostly just guesses, estimates and speculation. I have no means of knowing Nephilim were AL speakers or how many AL speakers there were. There were around 1,000,000 great pyramid builders living at one time and it looks like as few as 20,000 spoke AL. Each of these individuals held positions of importance and status. They were greatly overrepresented in the workers who actually built the pyramids.
The simple fact is very very little is actually known. This was caused not only by the change in language but because this change resulted in the destruction of every single book written in AL. People venerated the ancients and knew they were very powerful so they studied the books to death. None were understood so none were copied. But interpretations of the ancient words were copied far and wide and these formed the basis of the Bible and the Coffin Texts.
I won't repeat this tomorrow unless it serves my purpose. This post is hardly comprehensive and there are many other reasons and facts that support the existence of Ancient Language.
