First order logic, set theory and God

Indirectly, yes. However, I'm of the opinion that causality needs to be appreciated in its totality - in other words, it's not the water that directly caused the ice to form but rather the sum of all phenomenon (nucleation, crystal growth, biochemical processes, and whatnot) + the water that has brought the necessary and suffi­cient conditions to the formation of ice.

WOW !!!    

Biochemical processes and whatnot - Will I find that when i do a google search on the formation of ice ?

The answer i was looking for was a loss of potential energy. The molecules slow down. As they do, they form hexagonal patterns and move a little further apart.
But what caused the molecules to slow down ? The water itself didn't cause the molecules to slow down. The environment itself got colder.
The environment changed. The loss of energy in the environment was the cause. That loss of energy affected the water, causing the molecules to slow down.

I could make a puppet show and put it on youtube if it would helpful.

I'll simply point out for completeness that according to Thomists, material causes are causes as well, and in this case, the water would qualify. I don't know that the poster is a Thomist (or similarly associated person), but it's best to rule it out first.
