I don't know why Greeks want to prove all cultures and civilizations came from other lands to Greece, some people from Iran/Caucasus came and built Minoan culture and civilization and then some people from the steppe came and built Hellenic culture and civilization!
It is not like that,
Summerrians found irrigation and primary agriculture
Aegyptians started to calculate the irrigation with sun and star positions
Akkadians started the law under religious nobility
Assyrians Babylonians .....
Minoans found the true meaning of trade and merchant and sea routes
etc etc
Now what we call Hellenic Helladic proto-Greek or classic Greek or Byzantine Greek (Romioi) is another aproach.
the Iran Neolithic and Anatolian Neolithic expansion is not historical and roleplay part, of Greek ethnogenesis, as also all the paleolithic and epipaleolithic populations
but it is part of population when ethnogenesis movements happened.
1)
to understand at Sesklo-Dimini we see 2 different style populations,
nearby each other, possible different farming and production.
but after ethnogenesis we consider them as one.
2) the Anatolian and Iran Neolithic is old enough and spread all over Europe
3) there are some populations like
Cycladetic and Minyan and eteo-Cretan etc who are considered (tottal or more) autochthonus comparing their era and others.
compare Britain, USA etc
At Minoan era only tin was the interest
at Roman era was more a jewel of victory to the winner,
but later Celts Saxons Normands etc etc
after their ethnogenesis, they make the first industrial country and top empire.
the early people of Britain when Minoans trade tin from British islands
did not make the English or Walles etc etc ethnogenesis.
but was present when England or Walles etc etc happened
watch Rome as city,
a few Patricians started a state and a myth,
they needed populations for works army etc,
as city grow all roads lead to Rome, becomes a sink of DNA
the more the rich, the more the sink, the more the luxury the mixing populations etc etc,
Roman becomes syonym of Latinoi, Etruscans, etc etc all Italians,
and maybe one day many patricians sons left the city,
So who is original Roman from th early founders?
but they are all Romans even after a century.
We do not consider G. Washington or B. Franklin as English, Dutch, Francais, no matter these could be their origins and DNA results
But as Americans cause they made the US ethnogenesis,
