Water and time. And weak rock also.

It's insane the amount of damage water can do. I've seen it cut through concrete and even granite. I work with a crawl space company and even humidity in the air is incredibly damaging. 1

I can see why you would think that. It's certainly something we've been told our whole lives.

Do you have any suggestions on why we don't see lots of other canyons that are similar? If this explanation is the truth then isn't every river currently in the process of creating it's own canyon? The world is full of rivers, why do we only have a small number of canyons similar to the grand canyon?

Maybe it was a strip mine for some ancient aliens.

I wanted to give you multiple examples. Those are stone staircases worn by feet. Over a couple hundred years. Feet may be slightly more abrasive than water but the water had a Lot more time.

And there's also at least some wind erosion in the canyon

Global Flood created a super lake over most of western US. When the water rushed out of the lake (as a natural dam that formed it gave way, it creating a 10 mile wide channel, which later cut the deep trenches as the waterflow grew less and less. Same with the plateaus. It is likely the earth was much smaller before the flood. Rapid Earth expansion is very possible.
