I consider 2000 years very recent in human history. Even 10,000 years is quite recent. Modern humans can directly match their genomes to DNA that is 50,000 years old but it is believed that our species existed 200,000 years ago.
For the great majority of our history, we had ‘society’ that was barely above the level of apes. The climate that humans and apes thrive in (warm and moist) ensured very few remains were left for us to study.
Much of what you stated here is open to debate and questions. In any event, we were discussing this in the context of a 600 year old bra, not a 6,000 year old bra.
I think you should read more historical accounts, and less theoretical deconstructionist “women’s studies” screeds.
