At what time does the Biblical story line pick up? Assuming two thirds of the earth is water and if there were a leveling of the mountains the water could cover the whole earth's surface; the point is, when does the story kick in? I'd know for some time it was first a water world but the writer says that it first was a land dominated world. But now and for billions of years we know it was the place for blue green algae aggregation....that was the life source for the first life until the pre cambrian fauna. Right so far? So first, please let me know the source of the "land first" idea; I need to read up.....I'm obviously behind the times. Still and nontheless, I'd question the timing of the water world concept. At some time in earth's history, amazingly coincidentally, the Bible narrative is the preponderance of a water world. At some point it was so. HOW did they guess that? I researched the Egyptian sources from the Old Kingdom and that helps a bit; they too knew the preponderance of water; but did they think it a water world?
