5. Therefore, God does not exist.
Here the premises do support the conclusion, but premise 2, at least, is problematic. In what sense does Dawkins think God is complex and why does this complexity require an explanation? He does not discuss this in any detail, but his basic idea seems to be that the enormous knowledge and power God would have to possess would require a very complex being and such complexity of itself requires explanation. He says for example: “A God capable of continuously monitoring and controlling the individual status of every particle in the universe cannot be simple” (p. 178). And, a bit more fully, “a God who is capable of sending intelligible signals to millions of people simultaneously, and of receiving messages from all of them simultaneously, cannot be . . . simple. Such bandwidth! . . . If [God] has the powers attributed to him he must have something far more elaborately and randomly constructed than the largest brain or the largest computer we know” (p. 184).
Here Dawkins ignores the possibility that God is a very different sort of being than brains and computers. His argument for God’s complexity either assumes that God is material or, at least, that God is complex in the same general way that material things are (having many parts related in complicated ways to one another). The traditional religious view, however, is that God is neither material nor composed of immaterial parts (whatever that might mean). Rather, he is said to be simple, a unity of attributes that we may have to think of as separate but that in God are united in a single reality of pure perfection.
Obviously, there are great difficulties in understanding how God could be simple in this way. But philosophers from Thomas Aquinas through contemporary thinkers have offered detailed discussions of the question that provide intelligent suggestions about how to think coherently about a simple substance that has the power and knowledge attributed to God. Apart from a few superficial swipes at Richard Swinburne’s treatment in “Is There a God?”, Dawkins ignores these discussions. (see Swinburne’s response to Dawkins, paragraph 3.) Making Dawkins’ case in any convincing way would require detailed engagement not only with Swinburne but also with other treatments by recent philosophers such as Christopher Hughes’ “A Complex Theory of a Simple God.” (For a survey of recent work on the topic, see William Vallicella’s article, “Divine Simplicity,” in the Stanford Encyclopedia of Philosophy).
Further, Dawkins’ argument ignores the possibility that God is a necessary being (that is, a being that, by its very nature, must exist, no matter what). On this traditional view, God’s existence would be, so to speak, self-explanatory and so need no explanation, contrary to Dawkins’ premise 3. His ignoring this point also undermines his effort at a quick refutation of the cosmological argument for God as the cause of the existence of all contingent beings (that is, all beings that, given different conditions, would not have existed). Dawkins might, like some philosophers, argue that the idea of a necessary being is incoherent, but to make this case, he would have to engage with the formidable complexities of recent philosophical treatments of the question (see, for example, Timothy O’Connor’s “Theism and Ultimate Explanation” and Bruce Reichenbach’s article in the Stanford Encyclopedia of Philosophy.

Alvin Plantinga also discusses this in his article The Dawkins Confusion Naturalism ad absurdum.
Now suppose we return to Dawkins' argument for the claim that theism is monumentally improbable. As you recall, the reason Dawkins gives is that God would have to be enormously complex, and hence enormously improbable ("God, or any intelligent, decision-making calculating agent, is complex, which is another way of saying improbable"). What can be said for this argument?
Not much. First, is God complex? According to much classical theology (Thomas Aquinas, for example) God is simple, and simple in a very strong sense, so that in him there is no distinction of thing and property, actuality and potentiality, essence and existence, and the like. Some of the discussions of divine simplicity get pretty complicated, not to say arcane.3 (It isn't only Catholic theology that declares God simple; according to the Belgic Confession, a splendid expression of Reformed Christianity, God is "a single and simple spiritual being.") So first, according to classical theology, God is simple, not complex.4 More remarkable, perhaps, is that according to Dawkins' own definition of complexity, God is not complex. According to his definition (set out in The Blind Watchmaker), something is complex if it has parts that are "arranged in a way that is unlikely to have arisen by chance alone." But of course God is a spirit, not a material object at all, and hence has no parts.5 A fortiori (as philosophers like to say) God doesn't have parts arranged in ways unlikely to have arisen by chance. Therefore, given the definition of complexity Dawkins himself proposes, God is not complex.
So first, it is far from obvious that God is complex. But second, suppose we concede, at least for purposes of argument, that God is complex. Perhaps we think the more a being knows, the more complex it is; God, being omniscient, would then be highly complex. Perhaps so; still, why does Dawkins think it follows that God would be improbable? Given materialism and the idea that the ultimate objects in our universe are the elementary particles of physics, perhaps a being that knew a great deal would be improbable—how could those particles get arranged in such a way as to constitute a being with all that knowledge? Of course we aren't given materialism. Dawkins is arguing that theism is improbable; it would be dialectically deficient in excelsis to argue this by appealing to materialism as a premise. Of course it is unlikely that there is such a person as God if materialism is true; in fact materialism logically entails that there is no such person as God; but it would be obviously question-begging to argue that theism is improbable because materialism is true.
So why think God must be improbable? According to classical theism, God is a necessary being; it is not so much as possible that there should be no such person as God; he exists in all possible worlds. But if God is a necessary being, if he exists in all possible worlds, then the probability that he exists, of course, is 1, and the probability that he does not exist is 0. Far from its being improbable that he exists, his existence is maximally probable. So if Dawkins proposes that God's existence is improbable, he owes us an argument for the conclusion that there is no necessary being with the attributes of God—an argument that doesn't just start from the premise that materialism is true. Neither he nor anyone else has provided even a decent argument along these lines; Dawkins doesn't even seem to be aware that he needs an argument of that sort.

Finally, if you're interested, Alister McGrath discusses Dawkins' issue with divine simplicity in a number of places in great detail. Rev Dr Patrick H. Richmond from the Faraday Institute brings it all together neatly here.
Hopefully that helps a bit.
