Byzantine Prince

Please try your claims being more rational.

First of all, saying "tracing before Osman" is just ridiculous. Osman was no Adam, he was not a sole father in any way. You may be referring to Ottomans maybe.

Secondly, Orkhon Scripts prove the existence of Turks at least lasting since 6th century. The first of the three epitaphs were erected by Bilge Khan of Gokturks. Second was erected by his son and the third one was by Tonyukuk.

For more info on the first state to call themselves "Turk" :

The same link proves the Huns to be ancestors of Turks as well, which was opposed in another thread before..

Result is clear.
