Why only one Grand Canyon

I'll go ya one further - if the earth is so old, shouldn't we find evidence of its age, in the form of multiple Grand Canyons, on more than one continent? Or was the Colorado river the only river in the world to have been around so long as to CARVE OUT A DITCH HUNDREDS OF FEET DEEP FOR SO MANY MILES? Uh... yeah. Doesn't it seem more likely that a single catastophic event would be responsible for the formation of a single anomaly? Please respond.

You mean like the lack of evidence of transitional forms in the fossil record? The truth is, we have no way of knowing for sure how long ago the global deluge occurred, but what we do have to go on is "mythological" evidence from the four corners. Such an event would tend to burn itself into the minds of posterity.

You are overlooking one detail, and I might be setting myself up here, but we are talking about an event that occurred on a global scale, with all the attending dynamics, none of which could possibly be duplicated in the course of "natural", observable history. Kind of like evolution, right? Seems more plausible for a one-time occurrence such as the flood to cause a one-and-only anomoly like the Canyon.

Come on, now. If this is to be something other than a civilized forum, I'll just take my brain and go straight home. We all know very well that by "transitional" is meant from one species to another. Evolution on a micro scale isn't what's doubted. There is no missing link, and there would have to be thousands. So just ease your finger off the trigger, crashfrog. Put the gun down. Let's be adults here, shall we?
