Missing the Entire Thrust of the Argument

After a passable first attempt, and a merely “bleah” follow-up (a typical misrepresentation of what scientists claim about the Big Bang), Eric Hovind really hits rock bottom (pun intended) when it comes to his third “Creation Minute” video.  See if you can spot the howler:

Perhaps if you’ve never studied high school geography you might have missed it, but Hovind’s questioning of how the Colorado River could have flowed uphill for millions of years to carve out the Grand Canyon demonstrates a profound (and wanton) ignorance of proven geological processes.

One of the first things you learn in high school about our home planet is that the Earth’s crust is always on the move.  The theory of plate tectonics—the notion that the Earth’s crust is made up of a number of individual plates that drift around and bump up against each other—was one of the triumphs of the geological sciences of the early 20th century.  Today, in this age of satellite monitoring, it is trivially easy to show that many parts of the world—most notably the Himalayas, the Alps, and the Andes—are rising as the tectonic plates they rest upon are being thrust upwards by the neighboring plates which are pushing underneath, like placing a lever below a large rock to lift it up.

This is almost certainly what happened to the Colorado Plateau before the formation of the Grand Canyon.  There is ample geological evidence to show that the Colorado River (or a predecessor) carved out the canyon as the landmass around it rose due to pressure being exerted from neighboring tectonic plates slipping below it.  Studies of canyon’s route across the plateau show that the river’s flow and direction was directly influenced by nature of the upthrust of the land going on around it.

Of course, it has taken many hundreds of person years of scientific research, and many thousands of published papers to build a good picture of how the Grand Canyon was formed, and even now some questions over the details remain.  But then Hovind comes along that dismisses all of that with a wave of the hand and cries “Inconceivable!” as he fobs people off with an argument from incredulity. 

If pressed, no doubt he will spout the usual unsupported and unresearched creationist claims about rapid deposition and erosion during the Great Flood, but that is no more than using a toothpick to attack the Himalaya-sized mountain range of scientific evidence arranged against him.  It’s worth remember that analogy when you next heard a creationist calling for an equal hearing in the science classroom.  The disparity in supporting scientific evidence between the two sides simply cannot be overstated.
