9/14 slidshow
They might of thought this because, the way the rocks are shaped in the canyon are very different then the rocks you see on the ground today.The earth started out as just a bunch of rocks together then formed into what it is today. The rocks in the canyon are the same ones that were here years ago that are still here today.
