OK, Thanks. But I still don’t get the sarcasm part. I mean, why do Egyptologists say they are puzzled if the cause of the decline is understood. I’m trying to understand the point of your comment rather than the history.
That was part of the sarcasm; Egyptologists are puzzled about a lot of things because they don’t change their minds based on finds, and tend to be in awe of ancient despots such as the pharaohs.
