Psalm 104:5-9 seems to also suggest against a global flood. Verse 5 sets the time reference to creation, verse 6 is creation "Day" 2's of water. Verses 7-8 seem to be a retelling of creation "Day" 3's land forming with mountains rising and valleys falling. Then verse 9 says that the boundaries of water were made so that the waters will not return to cover the earth. Now this is a Psalm, so we have to allow for a bit of poetic leeway. But it suggests to me once the creation events were completed that water would never cover the earth again. Which suggests the later Noah flood wasn't global.
Perhaps the best evidence for a regional flood is Genesis 7:22's use of the Hebrew word "haraba" for dry land. A word that doesn't have a definition for planet like other Hebrew words do. That's the scope of the flood where, as the verse says, "Everything on the dry land, all in whose nostrils was the breath and spirit of life, died." (AMP version) The choice of the Hebrew word "haraba" should probably best translated as "...on the region of land...".
“Day” 3’s land forming with mountains rising and valleys falling. Then verse 9 says that the boundaries of water were made so that the waters will not return to cover the earth.”
This strengthens my belief that I posted in 51.
“And if the waters were to burst forth, what would replace its volume in the mantle?”
I believe the continental plates shifted cataclysmicly sliding and riding onto one another thus creating the mountains we have today. Pretty much the same thing the secularist believe but they believe in millions and billions of years... I believe it was very rapid. The land would have subsided or sunk and the some water would have stayed on top forming the oceans.
Events happen underwater even to this day, we know this because we have huge underwater rockslides that create tsunamis.
