It's the same old story- people don't always write down clearly with precise dates and unbiased viewpoints what happens to them...if they write at all; but nature and physical forces operate without bias, and the evidence they leave, once interpreted, can often clarify details in a way that no SWAGs* can ever manage.


Piecing together 'history' from human remains and pottery and ambiguous 'records' is a fine project, but it must always be refined by clear data from the physical sciences. I am always amused by those who get their professional egos mixed up in their research and 'reject' new findings instead of just trying to integrate them.
