Thanks for that. The problem here is that the flat earth interpretation doesn't work because of translation issues.
The flat earth was the general view until the end of the middle ages, even if one or two wise old Greeks had thought it round in the past.
I'm certainly not aware of any cosmology from three thousand years ago that thought the world was spherical. None of those quotes on that link suggest anything but a flat earth. To them the earth was immovably fixed at the center of creation and the sun, moon and stars went round it. And you could have a Noah's flood, because afterwards all the extra water would flow off over the edges.
And the sky was the firmament, a hard dome that you could walk on and to which the stars were attached such that if they come loose they'll fall to earth. There was no concept of heliocentry, gravity, orbits, satellites, planets, deep space, stars or galaxies.
Galileo in the 17th century was accused of the heresy of heliocentry. He denied (not altogether truthfully, I suspect) that it had never crossed his mind.
And Elohim said, Let the waters bring forth abundantly the moving creature that hath life, and fowl [that] may fly above the earth in the open firmament of heaven.
Genesis 1:20
But the gods of Mesopotamia, those of the Sumerians and those of the (Semitic) Akkadians and in due course Babylonians, were in place long before Yahweh appeared on the scene around 1500 BCE. The science of the (Semitic) Canaanites, including the Hebrews, would have been basically Mesopotamian. Indeed they got their Noah's flood story from the lore of Mesopotamia. It's mentioned in the Bilgames / Gilgamesh stories, for instance. If I recall correctly, a Sumerian impress seal from 2500 BCE or earlier carries an image of Ziasudra, the Noah character.
