How would you qualify a 'message' as real and significant? How would you disqualify one? Is Homer or Shakespeare real and significant?
Let's see if I understand: you don't understand the language, the archaeology, the history or the changing culture, but you want to debate that the 'message' is 'real and significant'. Are you serious?
You mean I do not KNOW the language, archaeology, history and changing culture*. You do not know if I understand it....or not.
*what's it mean I don't understand changing culture?
