One of the hotly debated issues about the flood of Noah revolves around the geology of the earth. If the flood was global then geologic evidence can be discerned. And, if the flood were global and recent (within the last 10,000 years) then evidence should be easy to discover the world over. The problem is, we have no markings anywhere of a flood that covered the entire earth. There is no universal flood layer.
Many that say the earth was covered by a global flood point to the Grand Canyon as evidence. Was the Grand Canyon, indeed cut by a flood? First it is necessary to say that floods are responsible for carving the earth in a specific way. Floods, especially a flood that covered the entire earth would never meander, unless the water had receded and slowed substantially. Floods usually carve relatively straight paths and would not be responsible for menders, as meanders represent a slow moving water source. Below are photos of what a meandering (winding) stream looks like and also a photo of the Grand Canyon which is an entrenched meander. In other words, the Grand Canyon is not caused by a flood, but is in fact due to a slow (meandering) body of water that carved it way through the rocks over time as the land was uplifted. Next I will consider more evidence to show that the Grand Canyon can not possibly be the result of a flood.
A meandering stream. These streams only form when the water has slowed substantially. Floods are the result of fast moving water as opposed to slow mendering waters.
This is an ariel shot of the Grand Canyon. It is clear that the canyon is an entrenched mender and not the result of fast moving waters from a flood.
