The claim of fine tuning is subjective. As I stated before, no measurement in physics is perfect. The amount of precision we demand can be increased or decreased at our whim. We could have an approximate measurement that has a huge margin of error and call it finely-tuned if we so desire. Theists, in particular, have a lot of such desire. They so badly want God to be an indispensable part of our universe's creation, so they see finely-tuned constants. They also tend to sweep under the rug the following fact: the vast majority of our universe is hostile to life, and they fail to consider that another hand in the proverbial deck might yield a better universe than ours, one teaming with life on every planet throughout the cosmos.
