sigh human memory is so short. It was only a few hundred years ago we last managed to wipe out several advanced civilizations due to inadvertent organic contamination. While Mars likely doesn't host sentient life, we ought at least show restraint exploring this new frontier until we are able to investigate and prove beyond a reasonable doubt that there is no such life existing in these regions of Mars.
