The flood story in the Bible was an adaptation of a story myth that was common in the ancient world. It has religious meaning, but no historic meaning. Proving that there was no flood has no necessary effect on religious belief.
'You simple assert your views without giving any connecting logic.'
The position is perfectly logical already. There is nothing to add. It is for others to prove that the flood story must be literal for belief to survive. It will be assumed that this challenge is too great.
