William Craig has sought to defend theism by participating in numerous debates. In a debate with the American philosopher Sinnott Armstrong, which is also published in a book entitled "God", Craig in his first reason tries to prove the existence of God by denying "real infinity" and relying on the concept of beginning and "the need of every beginning for a cause". On the other hand, he takes Big Bang as a witness to his claim, but Armstrong rejects Craig's argument by referring to the existence of real infinity in the outside world and the existence of scientific evidence to negate the implication of the Big Bang on the beginning of the world. Based on this, when it is not possible to properly use experimental evidence as a proof of theological reasoning, such methods can put the belief in God in crisis. Therefore, lack of establishing the correct interaction between theology and science can be considered one of the most important weaknesses of Craig's argument on the existence of God. Finally, by introducing a scientific model, it is possible to provide a solution to establish a correlation between science and theology in such a way that theological evidence matches with experimental evidence and external truth, and no contradiction threatens the belief in God.
