Questions:
Did Noah know that the earth is round?
How big did he think the earth was?
Did the North American Indians before the 19th century know the earth is round?
How big did they think the earth was?
If there was an Indian legend from a northwestern tribe that there was a huge flood that covered the whole earth, and archeologists found that there was indeed a catastrophic Columbia River flood the filled the entire Columbia Basin to the tops of the Gorge, would that not be something significant?
If a nomad found himself out in the middle of a body of water and could not see land, might he have thought the whole sworld (as he knew it) was flooded and so that's the way he told it and the story would be told from generation to generation? (Bedouin still tell stories that go from generation to generation.)
Is it not at least interesting that science does concur that an extraordinarily catastrophic flood occurred in the region where it is written that Noah lived?
