Yes. I’ve told it to you more than once already. Germanic is not in the picture.Would you please tell me your own theory about the language of Gutians and other people who lived in the west of Iran? Armenian, Indo-Iranian, Greek, Slavic, proto-Indo-European, Akkadian, Hurrian, or all languages except proto-Germanic?!
There were PPIE there. Possibly around the same time or shortly afterwards Kura-Araxes who I think became Hurro-Urartians. You dismissed this for some reason, even though there’s legitimate speculation there were Hurrian-like people in northern Iran and Kassites may have spoken a Hurro-Urartian language.
I think there might have been some early IE “straggler” language spoken in Iran/Zagros, that could be Euphratic and possibly became Gutian. Or Gutians may not have been IE at all...not enough data to be conclusive.
I think Armenians (Hye tribe) entered the region between 2500-2300 BCE with the Greeks. Greeks went westward. The Armenians stayed in the South Caucasus and would have reached Urmia. There may have been an early Armani tribe which would have been partially Armenian but centum and descended from PPIE and possibly not Steppe-derived. They could have been the Euphratics.
Indo-Iranians entered around 1500 BCE, possibly a bit before. Iranians proper entered sometime between 1400 BCE and 800 BCE.
I don’t see any reason to think Slavic was in the Near East ever. Nor Germanic. We know the Celts came during the Hellenistic period and settled in what is now central Turkey.
Besides Anatolian (but maybe Anatolian), possibly Euphratic (if they existed), possibly Armani (if they existed), and possibly Gutian, all IE languages derived from Steppe-populations who partially descended from Armenian/Georgian-like people from the region of modern-Armenia who migrated north. The respective language families—Celtic, Balto-Slviac, Indo-Iranian, Armenian, Greek, Germanic—derive from dialects formed on the Steppes/North Caucasus that expanded into Eurasia. Indo-Iranian developed in modern Russia/Kazakhstan, likely.
There are many Indo-Iranian languages and there is a record of written Indo-Iranian going back more than 3000 years. It’s pretty easy to establish where they originated from and track them using comparative linguistics and genetics. As a distinct language branch they did not originate in Iran. Neither did Germanic, which we, again, have literally zero evidence for having existed anywhere outside of Europe.
