3, The Kurgan culture (primitive Indo European culture) originated in 4300 BC did affect many countries in the whole Indo European continent. The ancestors of the Ashina family came from Gaochang. They may indeed be the descendants of the Kurgan people. But you can't say that kurgans are Turks. According to your logic, you can even say that the African ancestors of mankind were Turks, and all human civilizations came from Turks.
what about Indo European ?
Indo European = descendants of the proto Turkic Peoples
Haplogroup P-M45 ( proto Turkic Peoples )
Time of origin : 45.000 years ago
Place of origin : Central Asia and Southeast Asia
Descendants : Haplogroup Q and R
Haplogroup P-M45 ( proto Turkic Peoples )
Haplogroup Q : Native Americans
Haplogroup R : Europeans
American genetic scientists have proved that Europeans ( haplogroup R ) and Native Americans ( haplogroup Q ) have proto Turkic blood ( haplogroup PM-45 )
DNA never lies

even KURGAN name is Turkic means: fortress, embankment, fortress, high grave
The earliest known Kurgans are dated to the 5th millennium BC
and have been found in Mongolia, Kazakhstan, Altay Mountains, Caucasus, Russia, Ukraine, Belarus, Romania, and Bulgaria
also many Kurgans in China
That means Turkic Peoples throughout the last 10.000 years, had migrated further into Euroasian steppes, Europe, America, China, India as well as Mesopotomia while bringing their highly intelligent civilizations to the indigenous populations
SUMER Civilization : SUMER was not semitic ... SUMER was turanoid
They came to Mesopotomia from Central Asia
who lives in Central Asia in the last 10.000 years ? chinese ? koreans ? indians ?
of course Turkic Peoples lived in Central Asia in the last 10.000 years
in Asia , only Turkic Peoples had migrated further into Euroasian steppes, Europe, America, China, India as well as Mesopotomia
even Turks founded 16 Empires in the last 2.000 years ( modern history )
in Afghanistan = White Huns
in India = Mughal Empire
in İran = Safavid-Qajar-Afshar , Great Seljuk Empire ( İran was ruled by the Turks between 960s and 1925 )
in Anatolia ( Turkey ) : Seljuk and Ottoman Empires
in Europe : European Hunnic Empire
Egypt , İraq , Syria was ruled by the Turks in the last 1.000 years
The Tulunids were a dynasty of Turkic origin and were the first independent dynasty to rule Egypt as well as much of Syria in 868
also Mamluks and Ottoman Empire ruled Egypt
ASHINA ( ASENA ) is the name of a she-wolf associated with the Oghuz Turkic foundation myth
She-wolf (Roman mythology), a similar figure in the mythical foundation of Rome ... because of Etrusks in İtalia
from Central Asia to İtaly via Turks ... Etruscan civilization ( the inscription contains the phrase Turskum ) Tursci - E-trus-ci
maybe after 3.000 years , in 5.021 Greeks,Chinese,etc will say Ottoman Empire was not Turk
