Like Jewish Physicist Gerald Schroeder, I also see that both the Creation Week of Genesis 1 and the physical record of a some 15 billion year old universe are true and consistent when one considers relativity and inflationary theory: Age of the Universe
On the Noah Flood, clearly I see that it was a flood though there may have been aspects (or provocations) other than water - including earthquakes, volcanoes, comets, fires, etc. And clearly I see that it was worldwide as the evidence shows.
The difference in my view and some is that I see it as targeted or purposed to destroy everything in which was the neshama - God's breath of life. More specifically, that would mean Adamic man and the beings described in Genesis 6 - and every thing they touched.
Well, it failed in its purpose, then, since the population was not reduced to 8 people.
