History is a ripping good yarn

1. If x has a great plot, then it is probably not the case that either (a) x was produced by no authors or (b) x was produced by a largely unstructured committee of authors.
2. Human history has a great plot.
3. Human history is produced by God or by no authors or by a largely unstructured committee of authors (= all of us).
4. Human history is neither produced by no authors nor a by largely unstructured committee of authors. (1 and 2, non-deductive)
5. Human history is produced by God. (3 and 4)

Evidence for (2) is just how good plotwise history books are even when accurate. If one disputes that human history has a great plot as a whole, one might take some smaller portion of human history, but nonetheless one big enough that an analogue of (4) holds for it (so, not a part of human history dominated by a single figure like Napoleon).
