Do you deny that Jesus said he would teach using parable?
Does a parable have to be actually true in order to convey an essential truth?
If you concentrate on the minutiae of trying to scientifically determine the correctness of the parable, you miss out on the essential truth that it is attempting to convey to you.
You sure are annoyingly (dare I say perniciously) “disingenuous” for a Bible scholar on the order of an apostle.
Get a clue: Jesus was not speaking about the creation and he was not speaking a parable when He uttered the words, “in the days of Noah.”
You know endless atheistic evolution factoids, yet you don't know much about the Bible upon which you depend for your understanding of the Savior you claim, Jesus Christ.
Shame on you!
Get your priorities straight.
