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

[Pat Mustard]

You're mistaking an effect for a cause. The universe isnt the way it is to accomodate the exisetence of humanity (as evidenced by the fact that 99.9% of the universe is hostile to humanity), but we exist because the universe is the way it is.

And the question is, why, against all odds is the universe the way it is? In my white/black ball example above, we had to get 5 black balls in a row. If you saw that happen, you would swear that the drawing was rigged. Why am I irrational to assume that about the universe?

The odds are quite likely not nowhere near as farfetched as you think. For one thing, as Rhythm has already pointed out, there are alterations to the fundamental constants that would make a universe more amenable to life. For another a lot of the constants tend to work together, thus if you change (for example) the heat at the core of a star the pressure variants would likely adjust accordingly in order to keep the fusion fires burning. Thirdly, even if universes with the right conditions were rare, and needed to be finely tuned, there are an infinite number of different tunings out there, so even if 0.01% of them able to support life will crop up millions of universes, all likely to be clustered in groups (thus increasing the likelihood somewhat, as you'd only have to hit the right area). And for a final piece, even if the universe is that unlikely (which it is not, the p-value of a universe happening which created life happening is exactly 1, as we exist) that comes nowhere to bringing us to god in any shape or form.

Look, we both know you're not interested in a proper debate here, other wise you'd not be bringing up the same stupid PRATTs you always bring up. So why not just drop the pretence of having a reason for your religious beliefs and acknowledge that they are simply that.
