Genesis 1:6-8
“God said, “Let there be an expanse in the middle of the waters, and let it divide the waters from the waters.” God made the expanse, and divided the waters which were under the expanse from the waters which were above the expanse; and it was so. God called the expanse Sky. There was evening and there was morning, the second day.”
This passage is from the opening chapter of Genesis, part of the priestly account of creation (P-source). It describes God's actions on the second day, establishing a fundamental structure of the cosmos by separating primordial waters with an 'expanse' that God names 'Sky'.
How might our understanding of the 'sky' and 'earth' be reshaped by considering ancient perspectives on their construction?
