A few comments:<br /><br />earthseed: Good post, I agree. Good to have at least one "voice of reason" in the thread.<br /><br />Leovinus: I can't believe chew-on-this's last image got approved. Not that I'm offended, I think his images are great fun. It's just that that last one drags the discussion a little too far into the gutter. Something I hate to see in the science forum.<br /><br />Stevehw33: As usual, although on the whole you seem intelligent and well informed, on this one point: the possibility of microbial life, now or in the past, on (in) Mars, you are inexplicably, fanatically, stubbornly, illogically, blindly, UNSCIENTIFICALLY bound to the notion that we know enough to make the declaration: "There is no life on Mars!" when a simple "I don't believe life has existed on Mars" would more accurately express the appropriate degree of certanty allowed by our present knowlege. <div class="Discussion_UserSignature"> </div>
