Uplift and early carving: The region was uplifted about 75 million years ago by plate tectonics, a process that also pushed up the Rocky Mountains. Some geologists suggest precursor rivers cut canyons into the landscape around 70 million years ago. 

Modern carving: The Colorado River began carving the modern Grand Canyon around 5 to 6 million years ago, and erosion by tributary streams widened it to its current size. 

Rapid erosion: The canyon's deep, narrow shape is due to the arid climate, which allows the Colorado River to cut down faster than rain can erode the sides, creating a more steep-walled canyon than a typical river valley.

What the Bible Says: 

He Putteth forth His Hand upon the rock; He Overturneth the mountains by the roots. He Cutteth out rivers among the rocks; and His Eye Seeth every precious thing.

Job 28 : 9,10 KJV

Think About it: Science is factual. It has, or is supposed to have, evidence to back it up. When it doesn't have the evidence, not to mention practical explanations to support what our own eyes see, we have to ask questions. If I'm driving a car, and it's supposed to drive a distance of around 300 miles on a full tank of gas, I'm going to have concerns if the thing runs out of gas after 2 miles. Same with this enigma of the Grand Canyon. If it is said to be so many millions of years old, even with the variables of erosion concerning the different rock layers, why is there such a huge, (pun intended) gap in the results?

What sounds more plausible: The Grand Canyon was able to resist the physical requirements of layer erosion by such a large margin as to hold together through millions of years defying science and geological principles, or that a Master Designer carved out the canyon very quickly, and more specifically, intentionally?

You decide!

Until next time...
