"The rain lasted 40 days. The longer period of time was for the lowering of the water level" (ref your post 92)
My reply :
Genesis 7:4,+12, +17 : "The flood was on the earth 40 days and 40 nights "
but Genesis 8:5 says :"and the waters continued receding until the 10th month , on the first of the 10th month the 'tops of the mountains' appeared."
This is literal reading. The Flood lasted both 40 days +40 nights 'and' 10 months(perhaps Noah took two Cruises, not one). Which do we teach in science? J or P? And why are you intentionally misinterpreting your source of 'all' knowledge ??
And was Moses on these cruises? He supposedly wrote all these versions of the same story.
Genesis 7:17 is speaking of the 40 days that the flood was on the earth AND the waters increased. It's a conjuction, not a contradiction.
