First, Hume rejects the analogy between the material universe and any particular human artifact. As Hume states the relevant rule of analogy, "wherever you depart in the least, from the similarity of the cases, you diminish proportionably the evidence; and may at last bring it to a very weak analogy, which is confessedly liable to error and uncertainty" (Hume, Dialogues, Part II). Hume then goes on to argue that the cases are simply too dissimilar to support an inference that they are like effects having like causes:
"If we see a house,… we conclude, with the greatest certainty, that it had an architect or builder because this is precisely that species of effect which we have experienced to proceed from that species of cause. But surely you will not affirm that the universe bears such a resemblance to a house that we can with the same certainty infer a similar cause, or that the analogy is here entire and perfect (Hume, Dialogues, Part II)."
Since the analogy fails, Hume argues that we would need to have experience with the creation of material worlds in order to justify any a posteriori claims about the causes of any particular material world; since we obviously lack such experience, we lack adequate justification for the claim that the material universe has an intelligent cause.
Second, Hume argues that, even if the resemblance between the material universe and human artifacts justified thinking they have similar causes, it would not justify thinking that an all-perfect God exists and created the world. For example, there is nothing in the argument that would warrant the inference that the creator of the universe is perfectly intelligent or perfectly good. Indeed, Hume argues that there is nothing there that would justify thinking even that there is just one deity: "what shadow of an argument... can you produce from your hypothesis to prove the unity of the Deity? A great number of men join in building a house or ship, in rearing a city, in framing a commonwealth; why may not several deities combine in contriving and framing a world" (Hume Dialogues, Part V)?

There was never something so obvious that Hume didn't doubt it, except of course his own certain doubt.
