Science does great in the realm of the study of nature. It deals with elements and qualities of "continuity." Creation, however, is discontinuous in nature. Things like forgiveness, inspiration, walking on water and parting the sea are all acts discontinuous in nature. They ignore the continuity of physical law (not science). Physical law is not science; this is what science studies. Continuity gives science something to study.
Where God is concerned, all physical law is subject to suspension, revision or outright breaking. Water from a rock in the desert, manna from heaven and similar miracles break with the continuity that science studies.
So, what really happened in Genesis 6-9? We could say that it's all myth and leave it at that, but where's the fun in that?
Did God use a force that looked like water? Did He use actual water, but took care of all of the apparent problems we see from a scientific angle? Yes, the Flood story could be entirely myth and a morality tale -- a warning wrapped in symbolism. But where God is concerned, all options are on the table.
Of course what you say is viable, but what are the consequences if true? God made a flood, but covered up all the evidence apart from a couple of paragraphs in some Bronze-age poem? God made all life in some apparent order within a week, but then sneakily played around with the geology and biology to give the appearance of evolution from a common ancestor? God made the Earth 6000yrs ago but rigged the evidence to make it all look 4500Mya? God performs all manner of crime against humanity but condemns me to hell if I go have a quick toss?
Let's face it - that God is a bit of a fuckwit.
