Tengri
is the name for the primary chief deity of the early Turkic peoples. In one Kazakh myth, Tengri is a pure, white goose that flies constantly over an endless expanse of water, which represents time. Beneath this water, Umay calls out to him, saying “Create”. Tengri awoke inside a shining golden egg. Then Tengri broke the shell of the egg and went outside. From the top of the egg, Tengri created the Sky, and from the bottom, he made the Earth. Tengri’s breath became winds and clouds; his voice became thunder. Tengri’s right eye became the Sun, and his left eye became the Moon.
This is my interpretation of mythological creature of Turkic people.
