There are just so many problems with this story it's not funny. Trying to take this literally is just like claiming that 1+1=3. Go to Wikipedia: en.wikipedia.org/wiki/Noah's_Ark to read about all the problems that Noah would have faced.

This leads to the question: is God such a sadist as to give just a mere human such a great responsability? It is clear that the person who wrote the story was a fantasy writer. He wanted to embelish a story that could have been written in three lines: "God clicked his fingers and all the evil people on the Earth died. Noah and his family remained and so did some of his neighbours. Moral of the story, don't mess with God."

If God is so powerfull why don't we see that power in the Bible? Why does he always have to delegate things to humans? The answer is the book is written by stupid humans that never came in contact with God and probably believed that the Earth was flat. And we are told by the church to believe them? You got to be kidding me...
