I can't believe that it is so hard for you to realize, that what you are saying is what you wish for, and has nothing to do with science trying to decipher where Slavic Homeland was. You are a Croat and a Slav, isn't it romantic, and feels good, if Slavic Homeland was always in the same area. It would mean that Slavs are indigenous to this area, that your ancestors always spoke the language and your genetic was always Slavic. How convenient and romantic for you. I'm sure that these cozy feelings are clouding your judgment.
All these above happened at the end of Roman Empire, when the first information about Slavs are written. There is no mention before these times. It means they came from somewhere, and this somewhere wasn't in Balkans.
Can you imagine that Greeks mentioned Keltoi (Celts) in far away lands, but they missed Slavs who lived in Balkans. That would be something!
Doesn't bother me where would be the " homeland" I taught that 'master' historian like yourself could come with some 'arguments" cause you said there are many proves and now you are saying they are trying to decipher Lol
who were the 'first Slavs" of yours,was the Sclavenes,Avars,Schyths,Getae,Huns,Antae,Cutrigurs,was the far Veneti maybe,who spread that speech,there was bunch many of them in that period in Roman historiography,many time even confusing the names of particular tribe in their historiography,do you know which of them which language spoke exactly?you can guess only,all of them were doing raids,if we know that Balto-Slavic or Slavic language is present for 3000 years less or more,i think it's this way-The version about the Slavs coming from ‘somewhere’ originated long time ago in a misunderstanding of the silence of the Greek and Roman authors about the Slavs as such Trubachev 1985.
