Regarding the origin of the various human languages spoken here on Earth, the hundreds of languages lost over time, and the dozens now spoken, and whether any of these languages came from the stars. None of the languages now spoken is from the stars. There are some which grew, over time, from the hominoids visiting from the 12th Planet, but these would not relate to the ancient Sumerian or Vedic languages often assumed to have a relationship to the language of the visitors. The language spoken by these large, human like, aliens is very guttural, and would sound like a series of grunts to mankind, were you to hear this. Where the Pleiadeans and Nordics, among others, can communicate vocally in a manner that humans can hear, their languages do not have a corollary on Earth.
