I believe Jupiter's moon Europa has been found to have water on it.
Also,
When the probe took photos of a ditch it had dug four days before, scientists noticed that about eight small crumbs of a bright material had disappeared. They concluded those crumbs had been water ice buried under a thin layer of dirt that vaporized when Phoenix exposed them to the air...
...Phoenix's robotic arm first revealed the crumbs about 5 cm deep in the trench called "Dodo-Goldilocks" on June 15. By June 19, they had vanished. If the crumbs had been salt, they wouldn't have disappeared, scientists said, and if the ice had been made of carbon dioxide, they wouldn't have vaporized.

Here let me highlight some of your "evidence"
They concluded those crumbs had been water ice Hmmm, they concluded. Not proved, not for sure, they guessed. Sounds like a hypothesis to me.
Water is on mars. Sucks for you.
The temperature on the rest could be prohibitive to water formation. Like mercury, where it is so hot water separates to hydrogen and oxygen.
Before you ask why it formed here unlike other planets, just realize if it hadn't formed here we wouldn't be having this debate so it is pointless.

And the radar you are referring to has been tested on Earth many times to find liquid water.
Here's some quotes from your articles,
The first one - The images show what
appears to be brackish water seeping from beneath the Martian surface.
The discovery, if confirmed, will mark a turning point in our exploration of the Red Planet
Oops, that one didn't work, lets go to the next one.
Second article - Updated June '07: The researchers have
retracted their claim about the possibility of standing water on Mars after readers pointed out the terrain lies on the sloped wall of a crater.
Uhoh, that's strike two. Shall we go for the Trifecta?
Third article - "
A key question is 'How did the ice get there in the first place?"
While I didn't find a smoking gun, so to speak, in this article I did find the same question I asked about the planet earth. These are scientists here, you would think they would know about all this O2 and H floating around in the universe just waiting to collide a bond making H2O.
Im sorry Raist but your evidence is extremely lacking and definately not what I would call proof by any sense of the word.
So from this we can say that your original argument of it "just happened" isn't going to work. Are we going to start debating comets now?
