A quick and simple (in every sense of the word) guide to Intelligent Evolution makes good use of our old friend circular reasoning, assuming its conclusions all the way to proving the existence of the intelligent designer, simply by assuming that A) DNA is an example of “design” and B) all designs require a designer. They could have saved a step, by instead of using two false assumptions, simply assuming their final conclusion in one step, but I suppose that would have taken the fun out of it.

The code contained in DNA
Is evidence, or so they say,
God’s handiwork, there on display, the product of His Mind.
It’s plainly seen by any fool
It’s more than just a molecule
But rather, a precision tool that shows that we’re designed!

This molecule contains the clues
Creationists can gladly use
To show we did not come from ooze, through natural selection;
No “nature, red in tooth and claw”
But God, in wonderment and awe
Created, like a man of straw, his image in reflection.

A “pattern” differs from “design”
In elements which we define—
If your examples don’t match mine, why, mine are clearly right.
Our genes’ designs are clearly code;
A blueprint—Man, or tree, or toad—
From information God bestowed, in His most perfect Sight.

This Holy Blueprint I assume
Is proof we’re woven on God’s loom,
Created by the one to Whom we’re in eternal debt
The fact that I assumed it, true,
Could leave my “therefores” all askew
But have I ever lied to you? I wouldn’t take that bet.

You might suggest my logic’s flawed,
That my conclusion’s over-broad,
Or go all out and call me fraud—I’m doing righteous work!
I figured “What would Jesus do,
To have God’s message shining through?”
He’d lie, and cheat, and misconstrue, and be a total jerk!

And what’s important isn’t facts
But saving souls, and so the tracts
Say “judge them by their righteous acts” like lying in His name—
My logic’s circularity
Is more than mere hilarity
It’s honest Christian charity… and really, that’s a shame.

Cuttlecap tip to PZ, of course.
