Kalam Arguments and Causal Principles The merits of this argument notwithstanding it doesn't get you to Craig's Jesus, even if valid. The best Kalam can do is establish there was a cause to the universe. Muslims use the same argument.
From Alex J O'Connor:
"We should assess the first premise: ‘Everything that begins to exist has a cause.’ This phrase, in all its unassuming simplicity, has the potential to strike its reader as a truism, but it pays to ask yourself an important and relevant question: when have you ever actually known something to begin to exist? Have you ever seen something begin to exist, or even heard of such a thing? You may be inclined to answer that this happens all the time. Just this morning my coffee began to exist — only, it didn’t really begin to exist at all, rather it was the product of a rearrangement of preexisting matter.
Keep in mind that if the kalãm seeks to draw a parallel between things within the universe beginning to exist and the universe itself beginning to exist, they must ‘begin to exist’ in the same fashion. To reiterate, for philosophical relevance the kalãm argument must deal with things that begin to exist from nothing. Since this was obviously not the case with my coffee, it is an inappropriate comparison. What, then, within the universe, has truly begun to exist (from nothing) at a particular point in the past?
Nothing. The answer is nothing. Energy cannot be created or destroyed, and thus nothing in physical existence ever ‘began to exist’ in the sense we are interested in. Not my coffee, nor my computer, nor my father, nor the Burj Khalifa. Even something as seemingly abstract as an idea cannot begin to exist from nothing, since ideas are ultimately nothing more than signals in the brain, and hence physical in nature. It is this realisation that allows us to dispel the first premise as founded on an equivocation fallacy, since the concept of ‘beginning to exist’ is being used, it seems, inconsistently.
Nonetheless, it might be said, this variety of matter and energy constantly rearranging itself must itself, collectively, have an origin. This is of course plausible, but this origin would consist in the very beginning of the universe itself, when all matter simultaneously began to exist. That is to say, no matter has ever begun to exist except when the universe itself came into being. The only thing that ever actually began to exist from nothing, then, is the universe itself, and even this can be confidently asserted only because of our previously granting an entire premise of the kalãm.
Consider the implications of this. If the only thing that ever began to exist (in the relevant sense) is the universe, then the first premise, ‘Everything that begins to exist has a cause’ becomes ‘The universe has a cause’, since the universe is everything that begins to exist, being the only thing that began to exist. It should be immediately apparent that this premise is identical to the conclusion, and thus the kalãm can also be rendered as follows:
Premise one: The universe has a cause;
Premise two: The universe began to exist;
Conclusion: Therefore, the universe has a cause.
As is clear, the second premise is in fact irrelevant, and the argument is now transparently circular. It says nothing whatsoever, since the first premise states the same as the conclusion, and therefore is not a functional syllogism, but a mere claim. It is a claim which, to be at all convincing, will require far more to support it than this unimpressive yet ubiquitous attempt."
