Well, if you don’t take it as exactly what the Word of God says, then you’re dismissing several things that Jesus himself confirms, namely about Adam and Eve (as he relates their creation to the basis for marriage) and also about the judgement that God rendered (the worldwide flood), in that the conditions of mankind will be like the time of the Flood when he comes in judgement again.
Another way to put it, is that Jesus knew it was true, as the Bible says, and spoke that way in His time.
Jesus knew that not even “one jot or tittle” is in error in the Word of God. Whatever it says is exactly as it says.
I’m quite happy being a Catholic-we are all entitled to worship as we wish, and I will not argue about how any individual finds God, as long as they do find Him in a peaceful way-we would not be in a muslim country...
The flood is more than a story-it is well documented in several ancient books besides the Bible, as well as in the actual archaeological/scientific record-it is as factual as the explosion of the super volcano at Toba, or the bones of a woolly mammoth-but I do not see that it relates to what we are supposed to eat.
