There are a couple of ways in which defenders of the cosmological argument can develop the argument so as to avoid the consequence of God having to also have been made. One way is to use a principle that whatever has a temporal beginning of its existence has to have a cause of its existence. God, as understood in the tradition, never had a beginning, but Big Bang Theory strongly suggests that the physical universe had to have had a beginning. Therefore, the universe had to have had a cause of its existence, but God doesn't need one.
The other way in which defenders of the argument avoid the problem is by saying that what needs a cause are the sorts of things that, if they do exist, might or might not exist. In other words, these things are called contingent beings. Physical things are contingent, but God, if God exist, is the sort of being who, if he exists, couldn't fail to exist. So physical things need causes, but God does not.
These are well-known maneuvers (though they certainly have rebuttals), but people like Dawkins seen to be unaware of them, and that weakens his case for atheism.

In each of these cases, one can back up to a far more minimal conception of what is required. But then it is very difficult to go anywhere with the argument in its subsequent steps. If B can be accepted only in a fairly minimal sense, then it is not at all obvious that D is true. Conversely, in the sense in which D is obviously true, A2 and B are just as obviously false. So the argument gains no traction.
To say this is not to say that it would not be desirable for Christians to have better, fuller knowledge on some of these points; nor is it to say that such knowledge is not available. But the hinge of the argument is the claim in A2 that Christians would need a set of G-beliefs in order to have a personal relationship with God. And Drange gives no good reason to think that this claim is both (a) true and (b) substantive enough to support his subsequent chain of reasoning.
