By 2000 BC the people at Ras Shamra were writing in 4 languages. What on earth are you talking about?
Ancient Language was spoken in many dialects that were, for the main part, mutually intelligible.
Language fractured in a million different directions as the pidgin forms of it arose. Each different version of pidgin language was distinct from others and dialects of each one formed. Even today we pretend there is only one form of English but the reality is I can't communicate here any better than others are. There are for most practical purposes about 7 billion different languages as proven by the fact that every individual on the planet will take a different meaning from this sentence no matter how many times it is translated.
Ancient Language was different and only one meaning existed for each sentence. If you didn't take that meaning the words just didn't fit together so you knew you didn't understand.
Ancient Language can't be translated into English any more than Whale, Beaver, or Chimpanzee. The first pidgin languages were already splitting by the Tower of Babel.
3500 BC would put the Tower or Babel ahead of Noah's Flood.
I doubt there was a "noah's flood". More accurately I believe this story is a confusion of reality. I could tell you what the reality probably was but you'll not believe me anyway.
You do know they built watchtowers all over the ME.. Surely you have seen them??
The "Tower of Babel" may have nothing to do with an actual tower or other structure. It is a confusion of reality. Perhaps the scholars sitting in their ivory towers issued a decree that ended Ancient Language.
AS WITH ALL THING I DON'T KNOW. It is far above my pay grade to know anything at all. I am merely telling you what reality has to be to explain the meaning in the Pyramid Texts and solve most of the mysteries of human existence. The simplest explanation is humans turned into
Homo Omnisciencis at an event that we call the tower of babel. It doesn't mean there was a tower or an invasion of heaven. I don't even know whether or not heaven exists much less if a tower might reach it. I have only reason and evidence with which to work and this is what they say; humans used to be animals and now we're stinky footed bumpkins.
