Then you should remember this day. Avestan seems to have a history similar to Hebrew:Avestan, an extinct Eastern Iranian language related to Old Persian and Sanskrit, which was used as a sacred language of Zoroastrian worship long after it ceased to be used as an everyday spoken language.
Remember the last time you were correct about anything?
Me neither.
Hebrew had ceased to be an everyday spoken language somewhere between 200 and 400 CE, declining since the aftermath of the Bar Kokhba revolt.[2][12][note 2] Aramaic and, to a lesser extent, Greek were already in use as international languages, especially among elites and immigrants.[14]
