where are those pics originally from? i've been watching this thread for a while and thats the first one that really had me like keep it up excellent read
Somewhere on Earth as the grass on the top of the hill and the city in the valley indicates, and as the source says that was posted below the images.
I believe bluebird was illustrating a photo editing point

I think that you can see, clearly, water.
At the same time, ESA’s Mars Express mission is continuing its investigations of Mars, painting a new picture of the 'red planet'. This includes the first ever probing below the surface of Mars, new geological clues with implications for the climate, newly-discovered surface and atmospheric features and, above all, traces of the presence of water on this world.

If you like, I can list the biochemical reasons why this is simply not possible (since it is my job to know!) but I suspect you'd rather play in the land of make-believe than learn a little science. The best big thing insearching for life on Mars is Lab-on-a-chip technology to search for biomarkers (indicators of life that still has NOT been found there yet!). I don't think 6-figure grants and years of development would have been spent on this technology if we had PICTURES of multicellular organisms! Yeesh! Why don't we all start here: What to lichens and plants release into the atmosphere that is NOT present in the Martian atmosphere?
A CASE FOR LICHEN ON MARS
We have a natural model for one possible martian life form close at hand --lichen. In fact, the lichen possibility was offered as a model for martian life long ago, and such organisms possess all the characteristics necessary for survival in the harsh martian environment. They serve as a good model for Mars life because their known characteristics satisfy virtually all of the criteria imposed by the nature of the results in both Viking LR experiments. on Earth. Lichens are the pioneers of vegetation and are frequently credited with the initiation of weathering over large areas.
It should be noted that many forms of terrestrial biota could inhabit Mars but for the apparent lack of liquid surface water and the difficulty in husbanding water from the atmosphere against the low vapor pressure. However, we should not close our eyes to the latter possibility. In juxtaposition, one might well imagine martian scientists looking down on Earth and saying: “There can't be any plants or trees on that poor planet, there is only 125 parts-per-million of carbon in the atmosphere!" I think the arguments are fairly comparable. We have found that lichen organisms can essentially--quite satisfactorily, in fact--replicate the LR results in all respects. And, while it is not appropriate to get into the details of these studies here, I will present some photographic material that suggests to us (under very close scrutiny) that the Viking lander images may in fact have provided evidence of lichen growth on Mars.
Lichen Detection Tests With Viking STL Imaging System
Because Viking mission operations were still underway as we were conducting these initial analyses, we took some lichen-bearing rocks to JPL and put them in a simulated Mars terrain model that had not yet been dismantled(15). We took pictures of them using the science test lander (STL) Imaging cameras (identical to the flight cameras), and Figure 1J-15 presents the results of that work (top); the picture at the bottom is a conventional photograph of the modeled terrain for the landing site, which included highly detailed foam duplicates of rocks at the site (painted to look like the real rocks). The greenish lichens on our sample rocks were less clearly visible than in Earth sunlight and resembled the Mars images. When we subjected these pictures to a color-saturation analysis similar to the one I spoke of in reference to the actual Mars images, the Earth lichens were again the least color-saturated objects in the field of view
At first glance, Microscopic Imager on Spirit Mars rover at Gusev Crater seemed to have found an odd, biological-looking feature. I
