I don't agree with that. Craig claims to show that there must be a start to the universe on philosophical/mathematical grounds. Even if it were proved, tomorrow, that the Big Bang had something preceding it, Craig would probably just say that there must be a start back there somehow. Craig's argument attempt to prove that the universe had a beginning uses arguments about traversing an infinite span of time to try to show that the present could never have been reached in an infinitely old universe, and Hilbert's hotel - a thought experiment involving an infinite hotel - to try to show that the existence of an actual infinity is absurd. I'm not supporting Craig here. His arguments are terrible, and the arguments I've just mentioned here are extremely unconvincing and flawed - but he isn't really just relying on the Big Bang: in fact the argument he is using is a variation on an argument that predates the Big Bang theory.



But this is just ignorance. Apart from that this nonsense about infinities is bogus, we can not make any informed statements about what "precedes" the Big Bang, which is so far a pretty strong barrier for further scientific inquiry and we do not even know whether time actually exists outside of the scope of the cosmos. He's talking straight out of his arse.

So Craig's "scientific" arguments for KCA are:

1. The big bang model predicts an absolute beginning of spacetime and is correct.

2. All alternative cosmological models lacking an absolute beginning of spacetime (cyclical/oscillating, baby or bubble universes/multiverses) are unworkable, not viable, or even physically impossible because inconsistent with the second law of thermodynamics.


Guess I was right after all; and I have no reason to think that Craig is simply innocently arrogant. He's surely been lectured on this more than once, disregarding that it's his responsibility to educate himself on science before using it in his arguments anyway.
