As far as I can tell, you've only stated the obvious, namely that water mantains consistency within it's known environment. Even where it is found in different states it retains its molecular composition.
I would maintain there are specific reasons - in fact you've pointed at least one of them out - why water is not found throughout the universe. You've just given another example of intelligent design.
By this time you are probably thinking that it is like grasping at straws to pin me down with an example where the universe exibits, or is controlled by only random events. I have yet to apprehend by my senses anything that does not demonstrate at least some degree or element of design, and even in those cases where corruption or non-design are apparent, they need not be designated as beyond reason, impossible to explain, or unworthy of classroom discussion.
Please allow me to throw another question at you. What is the relationship between design and intelligence?
At that level of reasoning, any non-chaotic phenomenon is an example of intelligent design. Sorry; I dispute that simple non-randomness requires an intelligence to create it. Ice crystallizes in beautiful forms from water vapor. It does so by following simple physical laws. Regardless of where you think the physical laws came from, the operation of those laws on a random system creates order from disorder; and in their operation there is no design. Therefore, it is clear that the creation of order does not require intelligence; it simply requires some regularity in the behavior of the system. And there is no evidence that the regularity in the behavior of the universe is designed.

Design could be stupid. Think Edsel.
