Theists: What is the most compelling argument you have heard for Atheism?

[Pat Mustard]

Yes, and it has also been conclusively proven that a) what you consider evidence for fine tuning is not evidence, and b) even if fine tuning were real there is no current way to lead from fine tuning to god (for example the multiverse hypothesis is a much more plausible way to explain fine tuning than the god hypothesis, at least the multiverse actually agrees with what we know of reality, your god hypothesis flat out contradicts it).

So again, what evidence is there of fine tuning?

You continue to misunderstand the term "finely-tuned". It is a simple summary of the facts that the initial constants are mind-boggling precise to allow for our universe and for life. It is not a statement of intention. It does not itself imply a designer. It is simply a handy summary of the facts.

What evidence is there for fine tuning?

If you multiply just a few of these odds together (to get a combined probability), you have a number with so many zeros, there are not that many molecules in the universe. So, chance is out.

Anybody who knows anything about statistics and probabilities knows that in order to get the cumulative probability of a number of different events simple multiplication of individual probabilities is a bonheadedly stupid idea. You ave to correct for many things first, such as the interrelation of the events, the likelihood of a different result having the same outcome and so on.

For the first consider working on a ward as a nurse for a year where the p value for a patient dying is .5 (50% chance). Over the course of twenty years moving from ward to ward with the same probabilities multiplication will give you a probability value of .5^20 an astronomically small probability. The real probability is much higher.

For the second consider you're a mother whose two toddler children have died. The police say murder because it is an unusual set of events you say SIDS because they died asleep in their cots. You're convicted of murder partly on "expert" testimony multiplying the chances of each child dying of SIDS as if they were totally independant events. Proper research shows double murder in cases like this are 1/2 as likely as SIDS deaths.
