Or not. Have a gander at the real Grand Canyon one day and ask yourself a few questions, like:

• how did those enormous, flat rock horizons get there, made of various materials, without as much as a dimple in them where a small creek interrupted the expanse?
• how did the tiny, little Colorado River get to carve out that big wide channel, uphill much of the way? Did the river form in the channel, or the channel form around the river?
• how did those huge silt deposits, consisting of material compatible with that missing from the Canyon, get to be heaped up downstream of it?
• why are many of the fossils in each layer have been aligned in one direction? Is Islam older than we thought, and they were all facing Mecca when they died? (-:
• and so on...

Geology is way overdue for another Harlan Bretz. Who wants to step into the breach?
