challenge: without using historical sources - written histories - convincingly prove to me that there were celtic, gothic, slavic and then turkish migrations into the balkans and greece via the north - and, even some low level movement of wayward iranians over this path, too.

i wish you luck.

but, we know it's true.

i think you need to explain to me why there weren't invasions into the balkans from the north during immediate pre-history, given that it was a constant throughout the historical period until the russians put an end to it via just existing in between - which was like the year 1500.

when something is a fixture of history for 2000 years, you need to explain why it didn't exist in pre-history, not why it did.
