dfrank,
As I see it, it still comes down to you saying "this looks like evidence for water" and the rest of us saying "not to us". You ask us to prove you wrong. First, that is not our responsibility - it is up to you to prove yourself right, and second, it is not possible for us to prove you wrong. If you have not presented enough evidence to prove your case to us, you need to get more evidence.
So there is not enough data to prove the case of current water on Mars. Maybe this just has to be left as "we don't know, it will require future data". And in the real world, that is science - heck, I've given that answer frequently to my bosses.
As far as my opinion about the question of water on Mars... I think there is massive evidence that liquid water existed at one time on the surface. The evidence is not just photos of things that look like water created them, but things like mineral analysis that shows phases that could have only formed in an aqueous environment.
The evidence that liquid water currently exists on Mars is much weaker - even NASA and other astronomers seem to be debating the point. It is borderline at best that the pressure/temperature conditions would allow it. And there is a big difference between transient water and more permanent. It seems to me that even NASA is waiting on more data.
That leaves me two final questions to you. First, even assuming (big assumption) that the photo you presented shows evidence for formations created by water, how do you know that this happened recently or a hundred or a billion years ago?
Second, where is the conspiracy? Do you think NASA secretly agrees with your analysis and is covering that up? To me, it is more a question of just waiting on more data before reaching a conclusion.
