Genesis 1:8-10

8 And God called the expanse Heavens. And there was evening, and there was morning -- a second day.

9 And God said, Let the waters under the heavens be gathered together to one place, and let the dry [land] appear. And it was so.

10 And God called the dry [land] Earth, and the gathering together of the waters he called Seas. And God saw that it was good.
