Dr. Craig is a liar.

4) The Universe is its own explanation and cause; the no-boundary theorem of Hawking and Hartle prove this;

Is that the scientific consensus, or just your opinion that it's what scientists ought to believe, or what?

Theirs is a mathematical proof, subject to inspection, criticism, and even, revision; their theorem is not a physical proof.  It's basically a conjecture, and while I'm no expert, their theorem is available to the the entire World to see.  Point is that completely naturalistic explanations exist for the Universe's origin, cause, explanation and meaning.  We need not invoke "god"; such is completely an optional and superfluous belief.  I would rather embrace that which I can see (mathematical equations and formulas, even though I cannot fully understand all of them, others do) versus that which I have no access to whatsoever (such as "the supernatural").

I'll remind individuals such as Steve that there are a lot of beliefs (and infinite number, in fact) for which there is no evidence.
