Life as we know it on earth is cell bases, DNA, and so on. If we did find alien life, are we sure we would recognize it? What if alien life is similar to iron, but our tests couldn't even detect some other unearthly element that makes it living. I guess my question is, since earth life is so unique and specific to us, how do weexpect to recognize "life" so unique and specific to another world? Could we have seen life on a planet millions of light years away, but not realized it because the details of photography are limited?
