It's so simple. The flood really occured just as the Bible says. Satan just hid all of the evidence.
Of course hiding all of the evidence was a much greater miracle than the flood. So God realized he couldn't let Satan deceive Man like this. God thought and thought and decided to have some men write a book about him to explain all of this. Unfortunately since God himself didn't write the book, a few details got left out. Satan laughed at him and said "It would be a miracle if you can get anyone to believe that krap". God got pissed. He told Satan "You just wait, if any of them do believe it I will give them everlasting life". So anyway I think this clears up all of those silly questions about the flood.
If anyone has any more silly questions. Just let me know, and I will clear them up for you.
