I am sharing information that I found on Kemetic language - Afropedia.world.  It originated in Ancient Egypt or Kemet.  language is recognized based on the time period that is used. There are six periods which include: Archaic Kemetian language (before 2600 BC), Old Kemetian language (2686-2181 BC), Middle Kemetian language (2055-1650 BC), Late Kemetian language (1069-700 BC), Demetic (7th century BC-5th century AD), and Coptic (1st century AD- 17th century AD).  Coptic language is still used in Coptic Catholic churches and Coptic Orthodox churches in liturgical texts.  This language is also found in the Bible.  Evidence of the language has been found on a tomb inscription as well as on papyrus the shows a treatment for asthma and other inscriptions as well.
