Because life on a totally different gravity, with totally different water and dirt ratios, with totally different materials.... would still select humanity as a form.... That's not how evolution works. Yes yes, it must be humans, and they must be anthropomorphic. Can't just be a simple left over critter of the Permian that may have been on mars. Can't just be some simple worm that's cringed to life some how. No, it Has to be flipping giants? good God is that silly. I'd be more willing to believe there are dolphins on Europa than to believe you at this point. There's more evidence for that than what you're presenting.
With your two mile large buildings you can factor in how life would consider a lumbering multi hundred ton form as naturally selected for the human form. This is not how evolution works, again.
Learn some biology, learn some anthropology, and most importantly, learn some common sense. Because right there are HD photos where you said did not exist, with deep analysis of so-call structure now clearly being sand dunes.... so you talk about giants and footprints? In a place with whirling desert winds eroding away everything that could have been left?
At this point, you no longer are taking evidence to prove something. You're bending evidence to suit your beliefs. This is irrational, and utterly disrespectful to serious discussions on what may have been on mars. Furhtermore, its blatantly ignorant of the data available.
The data speaks for itself. There is no evidence for civilization on mars. Life, yes, there is plenty of proof for it. Proof that it may even still be there. But no proof of civilization. Sorry to burst your bubble, but science and technology trumps myth. Every time. And all proof says Mars never got beyond it's equivalent to the Permian, if anything at all. The last rivers ran dry with the dinosaurs died, and that doesn't leave a whole lot of room for much life of any interest.
