Please, don't think only in graphical arguments; planet geology shows that
is so posible that Mars could have water long time ago. It's orbit, solar
activity, planet size, mass, etc, looks like a planet which MAYBE had a
consisstent atmosfear. And, (please, read carefully) this is the theme which
I tryed to discuss: if we supposed that time ago was life on Mars, were
would be rests of that life today? And, to answer this, you should to know a
little bit more about planet geo history, to aply your great mic knowledge.
You look like if you'd need a colony of martian bac on your desk to begin to
think on the possibility of martian life.
Please, if you can't apport anything interesting to this discussion (which I
think is beggining to be finished :) ), don't post here, and mail me if you
want to talk about some other aspects.
Nice to read you. * Albano *
