newruz in central asia

Where did or from who newruz originated?Today from indo-europeans only iranians celebrate newruz.But, altough there had not been any cultural interaction between todays iranians and turks of central asia in the past all the turks in asia celebrate it.If there had been a cultural interaction between via schyts why do not todays europeans celebrate it?English and other european people claim that they are desdencent from alans, sarmatians, schytians.Isn't it silly?There is a kurdish mythology about saying that it is the day their one hero fight against a vassal king.But on the other hand there is not any kurdish record about kurds history and it is known fact that iran is ruled more than 300 year by turks.there is turkish mythology which turks survive from a place from melting iron mountains or iron sources in a mountain and this is the reason they tell why they are celebrating it.(is it true that it is mentioned in Quran by telling about dulqarneyn?looks more believable than kurds mythology)Where did turks get it?Is it a distinct celebration from newruz because they celebrate it at the same date with iranians?

Norooz or Nowruz is a Iranian "holiday" wich is celebrated by many central asian Turkic country's (azerbaijan and some in Turkey) also.

there is turkish mythology which turks survive from a place from melting iron mountains or iron sources in a mountain and this is the reason they tell why they are celebrating it

this is true, youre talking about "Ergenekon" myth, many people who wants to claim nowrooz as Turkic holiday come up with this, wich is silly.

Note; zagros Tashkent isnt full persian originated, tash = stone wich is Turkish and kent = city in persian i guess.

I know the main name of Tashkand was Chach, & after arab changed to Shash then Tash
