Discussing with Faith reminds me of Bassanio's comment in The Merchant of Venice : "Gratiano speaks an infinite deal of nothing ..... His reasons are as two grains of wheat hid in two bushels of chaff - you will seek all day ere you find them, and when you have them, they are not worth the search."
As far as I can see her argument is "The Flood did it in a way that it did therefore it did it"
