William Lane Craig diagnosed.

[Jehanne]

It's all relative, of course.  Compare yourself to that carpet cleaner and then do the same comparison between Craig and someone like Sean Carroll.  With respect to the latter, he is a professor of theoretical physics at the California Institute of Technology.  Craig was a communications major who went onto Bible college for his "graduate" studies.  Just do a comparison on the admission rates of Cal Tech and any Bible college.  Relative speaking, Craig is "unskilled".

But don't you think Craig knows that? 

Here's what he's good at: 
1. Making his followers feel like he has defended God well enough that they are vindicated. 
2. Obscuring the ways in which his relatively sophisticated god differs from their crude one, so that they can believe their god is the one he's been defending.

That's what he does.  That's what he's good at.  He doesn't pretend to himself that he knows theoretical physics better than Sean Carroll.

Judge for yourself:

Let me raise two concerns about this model. First, not only are the production mechanisms of such baby universes admittedly conjectural, but such a scenario violates the so-called unitarity of quantum theory by allowing irretrievable information loss from the mother universe to the babies. Stephen Hawking, apologizing to science-fiction fans everywhere, came to admit, “There is no baby universe branching off, as I once thought. The information remains firmly in our universe.”[18]
Second, Professor Carroll’s solution provides no convincing answer to the Boltzmann Brain problem. Since the mother universe is a de Sitter space in which thermal fluctuations occur and since baby universes grow into de Sitter spaces themselves, there’s no explanation in the model why there exists a genuine low entropy universe around us rather than the mere appearance of such a world, an illusion of isolated brains which have fluctuated into existence out of the quantum vacuum. These and other problems make Professor Carroll’s model less plausible than the standard solution that the universe began to exist with an initial low entropy condition.
Skeptics might hope that quantum cosmology might serve to avert the implications of the second law of thermodynamics. But now a new singularity theorem formulated by Aron Wall seems to close the door on that possibility. Wall shows that, given the validity of the generalized second law of thermodynamics in quantum cosmology, the universe must have begun to exist, unless, as in Professor Carroll’s model, one postulates a reversal of the arrow of time at some point in the past, which, he rightly observes, involves a thermodynamic beginning in time which “would seem to raise the same sorts of philosophical questions that any other sort of beginning in time would.”[19] Wall reports that his results require only certain basic concepts, so that “it is reasonable to believe that the results will hold in a complete theory of quantum gravity.”

Aron Wall is, if you look him up, a post-doctoral student in physics.  Craig, a communications major, has no business talking about "quantum gravity," an area which he knows nothing about.
