Ancient Turks had a peculiar idea about the origin of life, society, man and nature. From their perspective, the world appeared in a strict chronological order. At the beginning the blue sky and brown earth had been created. Later human sons had arisen between them. Finally, Kagans had towered over the human community. At the same time the blue sky was a symbol of Tengri, supreme creative force, who managed the destinies of particular person, nations, states and Kagans.
