What on Earth has that got to do with Bayes' theorem? What's your prior? All you did was re-state the anthropic principle.

- fenomas 11y agoI think the point is that there's no question of causality between values of constants and the existence of life, just conditionality, which is what Bayes knows how to talk about. That is, the anthropic principle doesn't try to "explain" why a constant takes a value. It just notes that the conditional property of us observing that value (given that we exist) is 1, regardless of what the unconditional property might be (or even whether it's variable to begin with).
