HOLY CRAP!!!!!! That's a lot of dumb shit for such a short post! You never heard of plate techtonics pushing up Everest and that it moves a little each year? Noah's flood formed the Grand Canyon? Ever heard of erosion? And just curious, where did all the water go?
Indeed I have heard of erosion. Erosion does not necessarily require your millions of years. Erosion can happen very suddenly. Ever see the results of a flash flood?
The top of the Grand Canyon is over 4,000 feet higher than it is where it enters the canyon. That means the river would have had to flow UPHILL for millions of years to support your claim. That doesn't happen in the real world. In contrast to all other rivers, we find the Colorado has no delta ( a place where washed out mud is deposited.) Had it washed out all this earth over millions of years, there would of necessity the requirement of a rather large delta.
Today we see two large beach lines at the top of the canyon. This means that before the flood there were two large lakes at the top of the canyon. These lakes overfilled and spilled very fast in a VERTICAL down-flow, not in a horizontal direction. This resulted in the steep sharp edges and high vertical cliffs of the canyon instead of the rounded gradual slopes normally found as result of a horizontal flow. The Grand Canyon was actually formed in a very short period of time caused by a tremendous quantity of water spilling over the broken walls of two lakes.
You shifting plates do not address the discovery of seashells on top of Everest. Do you realize Everest is quite some distance from an ocean? My father-in-law used to operate a front-end loader for the county. He was loading dump trucks with red clay from a huge clay quarry when he cut into the quarry bank and found oyster shells embedded in the red clay bank. That quarry is some 50 miles from the Gulf of Mexico.
Where did all the water go? A lot of it is still with us. They call them oceans, seas, gulf, lakes, etc. Most of the earth is still covered with water. Some of the ocean is quite deep, from seven to twelve miles deep in places. The world before the flood had very little seas if any. At present it is very dry in Pensacola where I live. I have to add water to my swimming pool a couple of times a week. This is called evaporation. The water from my pool may be deposited upon New York City by the way of rain or snow fall one day.
