      There is a variety of live and highly evolved being living at both Mars
      Rovers sites.I have been gathering pics of them.Some yahoo groups don't give
      me easy access to post(open posting) so that I can't simply say check the
      PHOTOS section of this Yahoo Group.If they were more open,then you would
      already know what life on Mars looks like.Check out the photos sections of
      Space
      people,eceti-chat,ShowInQuotes,Punktress,nasa2,space_expedition,abeginnersclub.There
      are over 300 pics posted in these few groups with Mars live beings and
      fossils.Jerry Lehane III Newark Delaware j.lehane@...
