I think a lot of the Great Flood legends are dim memories of a possible asteroid or comet crash off the US East Coast around 10,000 BC that may have caused massive flooding of the eastern Atlantic shoreline from impact-generated tsumanis. It also could be the result of early humans watching ice dams collapse from the receding glaciers at the end of the last great Ice Age, which flooded huge swaths of land.
That seems more plausible.
Big difference between melting ice glaciers and rain. (But the evolutionists need their story to fit in nicely).
There are a lot of numbers for mere storytelling - or is God creating a time line of events and history?
- "upon the earth an hundred and fifty days"
- "Fifteen cubits upwards"
- "forty days and forty nights"
- "six hundredth year...second month...seventeenth day..."
- "in the tenth month , on the first day"
- "and in the second month, on the seven and twentieth day of the month"
- "in the six hundredth and first year, in the first month , the first day of the month" - "thou shall take to thee by sevens...not clean by two"
