If you compare words in the Old Persian language of the Avesta religious texts to the Vedic Sanskrit spoken anciently in the Indus Valley Civilization, it’s obvious that the likeness of many of the words came from the same indo european (japhetic) ancestor, a son of Japheth (see Genesis 10) named Madai (his progeny in Persia known as the Mada or Medes), though interestingly the Hindus made the devas (devils) good, while the rest of the indo european speakers saw them evil, diabolical, diablo, the devil, whom the Avesta calls the evil daevas.
