"Intelligent design" is just another attempt to prove that a God exists. When stripped of all its verbiage about "irreducible complexity" and "specified complexity", it comes down to "I don't understand it and you can't make me understand it." 10-yr olds have this reaction to fractions, too.
At the core of ID is a circular argument: to whit, " I believe in a God that makes life. I see life and this proves my god exists. I cannot imagine another god or naturalistic way to explain life. Therefore evolution is false and my belief is correct. My god-faith shows that evolution is false. Therefore god exists."
26-23 in triple OT
Granted, faith in God is indeed faith and therefore the reasoning may be considered circular, but no more nor less so than for naturalism. As in, "God doesn't exist, yet here we are, so we must have evolved through some process which God had nothing to do with."
