Medieval Muslim scholars developed one of the most famous versions of the cosmological argument, known as the Kalām argument. It asserted that the universe had a temporal beginning — a proposition that philosophers typically sought to justify by showing the logical or mathematical absurdity of an infinite regress of cause and effect. The argument concluded that the beginning of the physical universe must have resulted from an uncaused first cause that exists independently of the universe. The argument was typically expressed in a syllogism:
[The American Heritage Dictionary defines a syllogigism as a form of deductive reasoning consisting of a major premise, a minor premise, and a conclusion; for example, All humans are mortal, the major premise, I am a human, the minor premise, therefore, I am mortal, the conclusion. In the case of the Kalām argument, the syllogism is this]
Whatever begins to exist must have a cause.
The universe began to exist.
The universe must have had a cause for its existence.
By further steps of reasoning, proponents of the Kalām argument deduced that the necessary first cause of the universe must transcend the physical universe (since a cause is necessarily separate from its effects) and must be personal (since only a personal agent can act discretely to initiate a new line of causation without its action being caused by a prior set of necessary and sufficient material conditions). Finally, proponents of the Kalām argument equated that first transcendent and personal cause with God.
I have taken this quote from Stephen Meyer’s book The Return of the God Hypothesis.
Are you still an unbeliever? Not convinced by the abductive logic I presented in my recent parts of this series, coupled with the additional tool of comparing the explanatory power of competing hypotheses sometimes called "inference to the best explanation".
Well let me take you to another scientific proof. This is a gift from Thomas Bayes, our 18th Century clergyman. Certainly being a clergyman fits in very nicely with this topic. But more relevant to the question of scientific proof, for those unbelievers, is the other hat that Mr Bayes wore – that of a mathematician and what his method can tell us about whether the creation of information for life is more likely to have been given by an intelligent designer – or multiple accidents.
