And God created Space between Water and Water

 ⁶ And God said, "Let there be an expanse between the waters to separate water from water." ⁷ So God made the expanse and separated the water under the expanse from the water above it. And it was so. ⁸ God called the expanse "sky." And there was evening, and there was morning—the second day.

Now this in being so I do not understand this verse from Genisis one bit. Why would God create an expanse between the waters instead of submerging the whole world in just an everlasting fluidity. If this was to be done then things would of evolved on much a slower scale. The reason slower evolution would benefit God is that he would be able to manipulate organisms much better due to a more stable environment for which not many chemical reactions can coexist with each other, meaning one reaction combining with another rare reaction will result in a diverse subject of the matter. Making it better for God.
