The way I look at it, proponents of this 'fine 'tunning' are arguing from an ignorance stance, and creating a reverse argument... Let me try to explain in simple terms: Life appeared a long time after the universe already existed, its the other way around, the Universe isn't 'fine-tuned', Life tries to tune itself to the universe, giving way to the evolutionary processes we all know (natural selection, etc)
If the universe was fine tuned to life as claimed, we would have life in EVERY planet, everywhere, its as simple as that...
