But "rain" is vaporized water (Mostly salt water) Meaning that A LOT of water needs to vaporate, but when water vaporize from the sea water, the ammount of water in the ocean falls (A very little, but if it were needed to rain 40 days water needs to vaporize 40 days so it would almost empty the oceans and lakes all over the world) It's called the water's cycle.
Short said: There've never been water enought on ze earth to rise the waterlevel to over 8.849 m

And:
1. How could all the animals and human breathe in that hight?
2. In the aftermath, how did Noah get food after the boat landed? There were only a few animals left.. If he just killed one goat... All goats would become extinct... And farming wouldn't really help (See point 8)
3. How did Noah get food for all the animals? Not all animals eat fish.
4. How could Noah keep sure that the Lions didn't kill all the other animals?
5. How is there still Birds, Spinders and other reptile animals when the bible said only animals who breathe with their nostrils were allowed on their boat.
6. Since the bible said only animals who can breathe with their nostrils were allowed on the boat, would all the whales, dolphins, ect. be on the boat?
7. All water were mixed when the flood came... Why is there still fresh-water fish?
8. Almost every three sorts would have been killed by the flood... Why is there still tons of trees... It would take thousands of years for one familly to plant trees all over the world.
9. If god knows everything... Why wouldn't he know the outcome of the flood... The bible says he was so sad about what he had done, he would never do it again.
10. Why didn't people just go onto their own boats? They could fish for food, and rain is clean, so they could drink that.
And Noah is a meanie for not inviting the Unicorns and Dinosaurs.
