The concept of design attributed to a canyon is a human concept? Or is it? Atheist folks like stu and other nature boys would have canyons designing themselves...attributing the very programming of nature having invested itself in itself by itself... ...that will happen, right? ...Like a computer program writing itself out of nothing...
Yes, the material properties of the canyon material against wind and water shaped the canyons. Is it really your assertion that anything else did??
Yes, it is called "emergent behaviour" , unexpected result from a computer program. http://en.wikipedia.org/wiki/Emergence may I suggest a remedial course or two at your local community college or maybe even a GED?
The Programmer... ...and you will ask "who created the Programmer" and I will respond "no one created the Programmer, the Programmer was never created" and then you will respond that you "don't buy that" and the wheel will go round and round...and your emoticons will go round and round just like longshot...
