There is a lot of detail in the bible.
How was it all remembered and recorded.
Much of the action took place before paper. Moses wrote all his stuff on stone tablets.
How did they ever remember all the details?
How did they remember it long enough to chisel it into stone?
How was all the history or at least the geneologies retained through the flood? Wouldn't it have all been lost?
Noah was a simple whatever... did he learn about all that preceded him and remember it?
