So what would they see...
..if they ran an average persons DNA through the retrieval method? A text file that says "I told you it didn't matter"? A long and complex equation that boils down to 42?
Or a copyright notice from a small company somewhere in the Lesser Magellanic Cloud?
 Were such a thing able to be located. Maybe they need to slurry together lots of DNA and pick the nicest^W best-preserved one..
