All creation stories come from the Sumerian Creation Epic.

The Enuma E'lish.

6 tablets of Action. 1 Tablet of Summation.

THE FIRST TABLET

When in the height heaven was not named,
And the earth beneath did not yet bear a name,
And the primeval Apsu, who begat them,
And chaos, Tiamut, the mother of them both
Their waters were mingled together,
And no field was formed, no marsh was to be seen;
When of the gods none had been called into being,
And none bore a name, and no destinies were ordained;
Then were created the gods in the midst of heaven,

FFW to THE SIXTH TABLET

When Marduk heard the word of the gods,
His heart prompted him and he devised a cunning plan.
He opened his mouth and unto Ea he spake
That which he had conceived in his heart he imparted unto him:
"My blood will I take and bone will I fashion
I will make man, that man may
I will create man who shall inhabit the earth,
That the service of the gods may be established, and that their shrines may be built.

Anyways, nearly all creation stories, including
genesis of the Bible, are merely loosely translated
Ancient Babylonian.

The 10,000 year old Sumerian Creation Epic, is actually
telling the story of our Cosmogony.

Look in the OP, everything under "The Dawn of Sumer"
I note several of the world's most puzzling astronomical
and geological questions being answered by the ancient
texts most civilizations base their beginnings on.
