Wouldn't you think there would be lots or errosion over millions of years?

Several geologists think that the Grand Canyon was not caused by a very slow erosion, but by rapid erosion that only a massive flood would be able to do. If you look at a side view, or cutaway, you will see that many points of the terrain go up hill and rivers do not flow up hill. There is geological evidence that does support this theory. The theory that it took millions of years to erode is an outdated theory made long before much was known and now with new technology scientists are starting to change their way in thought about this. Some scientists are die hards though and refuse to change their beliefs just because of ignorant stubbornness.

I don't know why you think the layers of the Grand Canyon are smooth, they are not. Maybe from a distance they appear to be smooth, but when you look at them up close they are anything but smooth. I have hiked inside the Grand Canyon eight times, including fourteen nights below the rim, and I know the rocks are not smooth.

Some of those thin layers represent thousands of years.....It seems major worldwide catastrophies only happen when they can support evolution...But if you mention worldwide sedimentary layers put down by instantaneous hydrolic sorting from a global flooding event, you get laughed at...I don't understand how anyone calling themself a scientist can say that things have occured at the same rate for millions of years and simultaneously believe that an asteroid or some other global event killed off the dinosaurs without affecting geology....Anyway, to answer your question, because it allows for all the time needed to have a beneficial mutation or for the loss of intermediate creatures, or for micro-evolutionary changes to add up to a macro-evolutionary change, or for my personal fav.

The erosion has something of a smoothing effect.

because it happened only about 6000 yrs ago or so...the Genesis flood.
