I wouldn't even bother calling it "noah's" flood, the whole idea of a boat doing what it was said to of done and achieved, is absurd, one has to either be completely ignorant of basic science, or perform an almost impressive amount of mental gymnastics in order to make the science "work".

The canyons were formed by glacial floods. If you want to say otherwise, you have to do the explaining to the entire scientific community. As scientific, commonly accepted facts and evidence far outweighs anything else that has been brought to the table.

"We" don't have anything to explain if you don't accept whats accepted by everyone else.
