Given the era, it seems likely that the collapse was the work of multiple angry gods. The author doesn't cover this possibility.
The closest to that would be the ideas in “ the origin of consciousness in the breakdown of the bicameral mind”

The people of that era would have thought so. The Iliad and the Odyssey (if they have any basis in reality) might be examples of that period seen through a lens of mythology.
People have always downplayed the number of things their gods can get angry about, while it often escalates beyond sustainability.
