we are all overlooking what might be the most obvious...uh, we're "guessing" that life "as we know it" may have existed on Mars....perhaps it still does....you have, what the scientists say "must be ice", because it's there one minute and gone the next time they checked...really, it has to be ice? Look at a time lapse of any populated place and do the inhabitants stay totally still all the time....what do we really know of life on other planets, perhaps they aren't forms we would recognize as life, perhaps they could look like...oh I don't know....ICE?
