Toward the end of the flood the unstable plates, over the now empty fountains, collapsed. This caused today’s ocean basins to form (Psalm 104:8) and the waters to flow into these basins (Genesis 8:2-3). For a global flood theory that answers dozens of questions which evolutionists can’t viably explain
