Well maybe
...but in reality while we know a lot more about our kind of Life than we ever did we know next to f*** all about any other kind of Life. We don't even know if anything other than DNA can sustain life - sure we know about PNA, TNA and RNA, but we don't have any examples of self-reproducing, metabolising organisms based anything other than DNA. Once we make some "alien life" of our own then perhaps we'll be a bit wiser as to Nature's blind stumbles, or artful motions, which led to Life. And that might tell us where it happened too.
