Dr. Craig is a liar.

That's what the scientific method can provide, the ability to verify, and more importantly, falsify competing hypotheses.  Religion has no such "pruning" mechanism, which is why there are so many different religions and creeds, all of which contradict themselves and each other.

There are a fair number of theories in science, which contradict each other (or are at least incoherent with each other).  I would also disagree that religion can't be falsified or corrected.  Just because something isn't repeatable doesn't mean that there is no reason or evidence behind it.  Also I think you are of a misunderstanding, that so many contradict each other.

Your statement about scientific theories is just misleading and false, and I would invite you to provide some examples.  General Relativity, Einstein's theory of gravitation, is being tested and retested and tested again and again right up to the present day.  No religion receives such scrutiny because no religion makes any predictions which anyone can test.  Theology is a predictionless academic discipline, and as the late Professor Carl Sagan once said, "Philosophers have no laboratory in which they can test their ideas."  As religion makes no testable predictions, religious belief is unfalsifiable.
