alone, and hundreds of billions of other galaxies, similarly rich with the kind
of environments we know to be favorable for our sort of life. Unless we're a lot
more special than at present we have any reason to think -- it seems likely that
other technological civilizations have reached this point and perhaps had these
kind of thoughts."</FONT></SPAN></DIV>

takes 10 billion years to evolve to the level of complexity associated with
humans. Then we may be the first intelligent civilisation in our galaxy. And
this could be the reason why when we gaze into space, we do not yet
see signs of other intelligent species. Or are they wrong [2]? Any
idea? </FONT></SPAN></SPAN></DIV>
