IOW, it is not the universe that is fine-tuned, but rather life that is fine-tuned (mainly through evolution once life has gotten started through other natural processes) to fit in the universe.
The Puddle explanation doesn't really address the basic argument. The fine tuning argument deals more with fundamental constants and starting conditions that allowed for stars, galaxies, planets, and complex chemistry to exist. If we were addressing an argument over how the Earth was designed for life, then the puddle analogy would be spot on.
