Trash helps recreate the environment people lived in and remove the ‘alien’ or ‘other’ dimension that interpreting the events may otherwise suggest. We often don’t realize how detached we are from a period until we observe an artifact or description of an event that doesn’t fit current behavior or the prevalent worldview.  This isn’t made any better when people try to sensationalize findings in an attempt to make them novel or scintillating to attract an audience or funding. If we don’t know real history or true behavior of the people we live among, then it’s easy to be duped by those types of charlatans.
