NO COMMENT: please, don't try to learn me which are the science fundaments.
And, unfortunatelly for us, maybe our job is not true science so...
Right now we have no direct

yes, some probes have been done on planet surfaces looking for life
activity, but, surfaces IS NOT the place to look in 'cause Mars and the most
of the planets has not atmosfear enough to stop nocive radiations from the
sun
All the evidence so far is

At this time, no body doubts that some geological erosion on mars surface
were caused for an hidrological activity. You should take a look to some
graphick documents.
As we get closer to the actual hands on phase of Mars
