The Big Bang

I often hear apologist, discuss how it is impossible for the universe to have an infinite pass, this is one of the favorite arguments of William Lane Craig's Kalam Argument for the existence of god. Yet he uses the big bang for his argument. However, for there to have been a big bang there must have been something to bang. You cannot bang anything, if there's nothing to bang. Apologist also like to use the second law of thermodynamics, which in a close system energy experience entropy or things gets worse over time. They argue that if energy has existed forever then entropy would have destroyed everything by now. However, the apologist forgets the first law of thermodynamics which states in a close system energy is neither created nor destroyed, it changes from one form to another. If something is created then it comes into existence and did not exist before and if something is destroyed it no longer exist. Therefore if energy is neither created nor destroyed then it is reasonable to conclude that they have always existed, and if something has always existed then it does not have a creator or destroyer or point to something else. Therefore one could argue that energy could have always existed based on the first law of thermodynamics. Think about it....
