What is your best arguments against a world wide flood.

Hi Im new on this board "Geology and the Great Flood". I believe that God controlled an evolution because of DNA-similarities.
But creation-books have convinced me that it was a world wide flood. (I was a pure creationist from the beginning.) Ive actually never heard arguments from evolutionists against this flood. So I would like to hear the best arguments in this topic from you evolutionists.

And what is the explanation to Grand Canyon. It doesnt look like the river of Grand canyon have deposited the layers. The layers are spread many many miles, the same stonesize lie with eachother. It looks like great waves have deposited them. The river is rather created by an initial crack.What about polystrata fossils and massive fossilgraves and the oil. You can argue that its AT LEAST large local catastrophies and not slow burying.
