The story as found in the Bible is straight forward and rather logical. Stores tend to go from straight forward and direct and morph into corrupted nonsense except for a few minor details here and there: Example of the straight forward: 8 people, whole world covered with water, God's judgement, and building of a boat and the saving of animals.
You do know that story, as you just described it, is an impossibility on multiple levels, right?
I do not see it any more impossible than building a ship out of reinforced concrete. And that certainly has been done. I note that there were cat kinds, dog kinds, cattle, horses and more than likely a very limited number of breeds. I see no reason that given the flatness of the original planet, that much of the water erupted from inside the planet and hit the planet in the form of comets, asteroids, and possibly a collapsing ice canopy/shield around the planet. The entire event seems more than scientifically possible --- it sounds highly probable.
First, as there were only "two of every kind", specifically for "repopulating" the planet, how do you suppose the animals were fed? Particularly the carnivores? Second, there is no evidence whatsoever that the earth, 6,000 years ago was "flat", and there is zero geological evidence of a global flood. Finally, there is the question of the Ark itself.
The Ark was, according to the Bible, 14 feet high, 450 feet long, and 75 feet wide, and in order for the Biblical account to be accurate, contained over 50,000 animals, 2 million insects, 7 people, a 600-year-oldman, and enough provisions for a year. Now, it may be difficult to comprehend what is wrong with this picture without a point of reference, so let's use the titanic, one of the largest ships ever built. It was 175 feet tall, 882 feet long, and 92 feet wide, and its full capacity was 3,547 people, and enough provisions for only a couple of weeks.
