Picture a puddle gazing at its hole and marveling: "This hole fits me perfectly—must have been designed for me!" That's the fine-tuning argument. Sure, the constants are razor-thin, but we only exist in the universes where they work out. We're the ones standing in the winner's circle, so of course it looks rigged.
And calling it "the whole book" doesn't help—you're still saying the book needs an author, then claiming the author doesn't. That's a special exception you only make for God. Give me one testable prediction that separates your designer from no designer, and we'll talk.
