Actually, if you think a bit and read scripture, the flood was probably the Black Sea (as the glaciers in Europe melted) and building an ark was probably the best thing to do to preserve the culture and the livestock.
And one last thing, primitive cultures around the globe worshiped the Sun God centuries ago and the world was relatively united in worshiping what gave life. The ancient virgin Mary was a "Rubinest(sp?)" woman with the testicles of bulls wrapped around her body. Things changed when men stopped hunting animals and started taking control. Now, people worship different flavors of Male Gods and kill each other based of those flavors. Supposedly, it's the Male human’s interpretation of God that is the driver. If you go to any city within the States and read through the local yellow pages, there are many twists of the different flavors of God. Moreover, there is competition for new recruits. All this is a perfect example of Entropy, maximum disorder. This makes the forces that drive modern mankind equal to the forces that drive the universe.
Uh huh, could be. The Black Sea hypothesis has some merit, and would explain where the story derived. However, it still does not explain the need for preserving species or kinds.
