I think these Bosnian pyramids have been debunked, BUT
What kind of historian says something can't be so because of a current understanding -- rather than investigating the information to see if the current understanding needs to be revised?
The professor's view probably has to do with the fact that there's no continuity of activity between the fake archaeologist's claimed 10K and the sudden appearance of actual durable structures. So I'm not sure why you're directing criticism at him, when this Von Danniken style amusement park builder isn't being held to any apparent standard at all.
