Posts here and here considered two reasons why Christians’ claim that their God created the cosmos is preposterous. A third reason is that –
God as creator leads to an infinite regress.
Christians like to assert that everything that has a beginning has a cause; the universe had a beginning therefore it had to have a cause. That cause – watch the unwarranted leap of faith here – can only have been have been their god. My previous arguments notwithstanding – that God needed to create everything from nothing (which according to Christians is impossible) and the immaterial cannot produce the material – the notion that god caused everything begs the question, as Richard Dawkins points out, of who caused his being. If, as Christians like to argue, everything has a cause then their god must have one too. Their assertion that he is the exception because, by definition, he has no beginning and consequently has no need of a cause is merely special pleading; why should he be different from everything else?
Christian apologists – William Lane Craig, for example – always assume that the first cause is their god, without a beginning and need of a cause. Their thinking goes as follows: everything that exists has a cause; the universe must have had a first cause; this first cause was somehow sentient; we are going to call this sentience ‘god’; this god must be our god, YHWH.
Yet they provide no evidence that there is, or was, a first cause; there could have been several contributory causes, including chemical, physical (gravity, for example) and activity on a quantum level. They then make the unwarranted assumption that this cause must have been sentient, again without evidence, and load this presumption with further insupportable connotations when they label it ‘god’. Finally, they make another leap of faith by claiming this ‘god’ is their god, YHWH.
This is all so much special pleading, insisting everything has a cause except the thing Christians don’t want to have had a cause. But God cannot be excluded; he too must have a cause (and indeed he does). So who or what caused him and gave him his start? And who or what created whatever it was that created god? Who or what created that? And on into infinite regress.
Those who offer such arguments put the proverbial cart 613.772 billion years before the horse. As Richard Dawkins says in The God Delusion, intelligence and creativity have only ever arisen as a result of evolution, specifically the evolution of the (human) brain. We know of no other means – there is no other means – by which intelligence and high-level creativity are produced. For a creative, super-intelligent mind to exist prior to the beginning of everything is, therefore, an impossibility. As I suggested in the second part of this series, the physical always precedes the immaterial; the natural world produced the advanced human brain about 200,000 years ago, and that brain has, ever since, projected its gods backward to the beginnings of the universe. This does not mean that a being without a beginning was actually there, much less that he produced the whole show. It means we know the cause of god. It is us.
