The next thing recorded in the Genesis creation story is that G-D spoke the firmament into being to divide the waters.
Genesis 1:6 G-D said, “Let there be a dome in the middle of the waters, and let it separate the waters from the waters. And G-D called the dome sky.”
Evening and morning was the second day.
What waters? Where did the waters come from?
We are watching the birth of all creation. First creator said get some light in here. Then she separated the waters to give her a workspace to put all of creation. The area in between the waters is called the expanse.
The next thing recorded in the Genesis record, Genesis 1:9 says, And G-D said, “Let the dry land appear……..Let the earth bring forth seeds and each yielding its own kind.”
And G-D saw that it was good. Evening and morning was the third day.
