V 9-10 "And God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so. And God called the dry land Earth; and the gathering together of the waters called he Seas: and God saw that it was good.”
You cannot build anything using water as a foundation—certainly not a lasting, happy courtship. In creation, in order for there to be a world with grass and trees and animals and man, God first created dry ground. The dry land provided the foundation needed to support all that God would place in His beautiful creation.
