Why only one Grand Canyon

No, that's evidence against the flood, because it means all the water on Earth can't cover more than 70% of the Earth's surface. Is it a boat?All we need to prove this global deluge is some evidence that it actually happened, and for all the evidence that it didn't happen (i.e. areas of the Earth that have never been flooded within the past, oh, 5,000 years) to conviniently not have existed in the first place. But that's really not going to happen, because the flood didn't happen.

There's thousands of transitional fossils. Where did you hear otherwise?What a silly thing to say. Well, no, the Bible says when it was supposed to have happened. But it didn't happen then. We know that, because the civilizations living at the time have no record that all their citizens were destroyed by a global flood. Which you'd think would be something they would write down, at least afterwards.
