I think you should consider becoming a professor of linguistics at a local university in your area

Your people can benefit from your profound knowledge

I mean, who other than you could have thought that languages change as people move from one place to other
While it is true that a given language does change as the population of people who use a given language DOES change as that population moves about----and encounters "other" people----my discussion was about your mistaken belief that Sanskrit came about---writing and all and then OTHER PEOPLE LEARNED TO TALK and WRITE from Sanskrit speaking (and writing) people.
Not an easy concept for you---but the fact is
that all human brains are so constructed and so function that LANGUAGE in all societies---
HAPPENS. The people of the Rhine valley--did not learn to use language from literate
scholars in or from India. Hebrew is a semitic language like Aramaic and Arabic. The ancient Egyptian language is not a particularly semitic language---but related to some extent. Because of PROXIMITY and INTERACTION between Egyptians and
Hebrew speaking people in ancient times---
there are some words in Hebrew that have
Egyptian origin but Hebrew did not EMERGE from some sort of Egyptian root. For that matter neither did it EMERGE out of Arabic
or Aramaic---it developed separately. Same is true of SANSKRIT AND GERMAN. Some day you will understand
