Those non-believers that came to their non-belief by observing what’s wrong with the world - as compared against the conjecture that it was created by God - or analyzed the arguments for God and found them fallacious, absurd, or otherwise double-plus-ungood, can probably guess what’s wrong with all of Dr. William Lane Craig's reasons to believe in God, but it doesn’t hurt to re-state it occasionally.
In a nutshell, you can’t conclude that god is the best explanation for any of the proposed “mysteries” that Craig lists, because God does not exist independently of his arguments. He can't be found by looking for him directly. He can only be imagined. If he can only be imagined, what good is he as an explanation?
Say, for instance, if Galileo had peered into the heavens and seen God staring back, you might consider that evidence that god exists. If every astronomer since Galileo peers into the heavens and sees God staring back, you might say that God most probably exists.
If Darwin had set sail on the Beagle and found that every species of plant and animal sprang into existence within the last few thousand years, you might infer that they where created simultaneously. If every biologist and botanist since Darwin found only evidence of recent creation, this might lend further credence to that inference. When the DNA of all animals is eventually found to be perfect, containing no junk and no mutations, you might further infer creation by something perfect that knew what it was doing. It could be the same entity that Galileo observed. It might be God, and that might bolster the argument further.
I could go on, but I don’t really need to - the examples become repetitive very quickly. Everything that every branch of science observes leads us to believe that our patch of existence expanded into its present form about 13.7 billion years ago. No where has a God hypothesis - any God - risen to become even a remote contender as an explanation. The imperfect - and predictable - way that the universe evolves and that life evolves indicates wholly natural origins.
God may be used as an explanation for mysteries when people like Dr. Craig speak, but he never appears independently from Craig's (or anyone else's) arguments. It’s as if apologists can’t think of plausible explanations to life's complicated questions, but the most fantastical explanation imaginable is perfectly acceptable.
It’s a mystery that believers don’t see this
