"In a few years at best?" I'm fairly certain it took longer than that. The "size of a state" is minuscule when compared to the rest of the planet. The Grand Canyon represents only a tiny fraction of the geologic column. I'll have to read up on hydrologic processes before I can answer your question. I'm sure you won't change the subject as I look for an answer, will you? You know. That little "bait & switcheroo" thingy you are so fond of baiting and switching to?
Meanwhile, I've also posed a question several times that never seems to get answered: How do theories of evolution demonstrate the process of evolution itself?

Go ahead, you old bluffer, you. I'll just suspend the conversation until you get back to me, so you don't get confused.
