That is exactly the point I was making, we are so far removed from what we
are excavating, not only in time but also from the mindset of the people who
created the site/artefact etc.
I can't get my mind around many of the ideas some of my fellow citizens have
about the modern world, never mind being able to fully comprehend (say) the
modern Japanese culture and religions, despite having a wealth of
information and access through modern communications.
How on earth can we expect to comprehend the culture and religion of a
society from which we are separated by 5000 years?
It is surely folly and hubris to think that we really can: however to make
sense of what we find we are driven to try, to interpret and explain in the
light of what we know and believe.
The main thing for an archaeologist is to have an open mind and be receptive
to alternative ideas and theories and be willing to change interpretation
as new evidence is uncovered.
