Oh my gosh! How much was spent for such a ridiculous ‘study’.
This sort of archaeology is very valuable. It can explain why events transpired, or what was it that actually happened. You will find some of this in, say, “The Fall of Rome: And the End of Civilization”, Ward-Perkins.
This is an examination of all sorts of archaeology (middens, potsherds, ruins, etc.) that documents the extreme declines in material culture, the collapse of trade and manufacturing, and impoverishment of diets, as well as massive population collapse. If you want to understand the Fall of Rome, I suggest that this book is as essential as that of the works of Edward Gibbon.
