you really make me wonder with astonishment and disbelief, where do turkish people get info from!!?? 
 Linking summerian with turks. What a nonesense ????!!! 
 My friend, the time when the Summerians were at the peak of their civilization (culture, writing, pottery, agriculture, metallurgy). Your people on the other part of earth were savagely busy butchering and raping other civilizations, and your own kinsmen. 
 The turks never had any sophistication and potential of advancement except the thirst of pillaging and destruction. 
 Your legacy of destruction, is second to none!!!! 
 You claim Scythians to be your ancestors. Is yet another nonsense. 
  Scythian are Iranians in origin related to other Iranian races such as Afganis, Kurds, Bakhtyaris, Tats, lurs, Baluchis, Ossetians, Persian, not only linguistically, but physically as well. 
 Majority of researches indicate that the Huns, Mongols, and Turks (related tribes) were all Asiatic (Mongoloid race, round face, small eyes) in their physical appearance. 
 Those turks that have a caucasian features have either lost their Asiatic traits from intermixing with other races (by force) or they are not turks at all, but turkicised. 
 The turks have subjugated many races in their conquests, and settled in what is now turkey, the homwland of Armenians, Kurds, and Greeks, and other indo European nations that are extinct today.. 
 even the Azarbijanis are not real turks, but turkicised turks. They have their own language, a pure Iranian Language, which is closely related to Kurdish and Persian called (Talish, or Tat). Although many of Azarbijanis do not even know that. 
 Saga, Scythians, Sarmatians, Sogdians, all these names are of people that lived in central Asia (close to savage turks and Mongols), with beautiful civilization shown in their artifact, the builders if Bukhara, Samarkand, and inventors of silk were all wiped out of the face of earth, by the primitive Turkish hordes. 
 Even the founder of Ottoman empire himself was not a Turkic himself, but a turkicised. 
 There is a portrait of himself that shows clearly his Indo European features (blue eyes, Blond, tall). Probably related to the Aryan (Iranian) tribes that were already assimilated. 
 In reality, for The Ottomans used the word turk, as an insult and degradation. Called themselves as Ottomans, Ottoman Empire instead of turkish empire. And majority of those that were famous turks were either Albanians, Arnout (Bosnians), Greek, Armenian, or Kurd origin. (all of course turkicized) 
 These facts are all well documented, and can be found in historical and archeological studies. 

 You can not fool the world of your stupid claims, we are at this age of computer and information advancement. It is 21 century my friend. 
 Get yourself busy reading.
