Why is water the only thing that expands when it is cold?

Because if it didn't, it would be heavier that liquid water and the ice would all sinkto the bottomof the lakes. The lakes would freeze solid from the bottom to the top. This would kill all the aquatic life and God would need to create new fish every Spring.
