You see here's how it works. A Christian will say that they will debate the issue using nothing more than reason and logic. With lots of confidence they'll step into the circle.
There is a back and forth but eventually they end up retreating to the land of no logic where certain things don't need to be explained and gullibility is a virtue. Often times they don't get there until they embarrass themselves. The analogy "it's like playing chess with someone who thinks you're playing checkers is a good one."
It makes you wonder why they just don't stay in the land of faith and leave it at that.
I'm sure there are more than these out there, but here are a few resources from some Christians who seem to be quite comfortable and good at taking the likes of Dawkins in his own lofty 'chess playing' venue.
I've blogged on it before, but I'll mention it again. Vox Day, in his book The Irrational Atheist, handily squashes the central argument Dawkins makes in The God Delusion.
Greg Koukl, of the organization Stand to Reason, does a fine job in exploiting the impotence of Dawkins' argument as well.
From the article...
Even if we grant (4) [Dawkins' premise - "The most ingenious and powerful explanation is Darwinian evolution by natural selection. The appearance of design is an illusion."] – a highly controversial point, given the amount of contrary evidence – Dawkins only succeeds in showing that the design argument fails. It’s entirely possible that other arguments succeed. Since there is nothing in Richard Dawkins’s line of reasoning that contributes to his conclusion, the central argument of his book is irrational.
