Genesis 1:2 says there was deep ... water... a flood of all things, long long before Noah ever breathed life. Well wonder WHY most on either side of the debate willingly ignore a flooded earth before it was made 'good'?
Water was the initial creation; then the water was divided.
The terms used in the Masoretic text speak of expansion of that water into the entire creation. It was definitely not a flood, but a birth.
