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

[RoadRunner79]

How is this god person supposed to set the physics?
what process did it use,?did it punch them into its celestial computer or are the theists just assuming that if no one knows, god did it is the default?

god is not the answer to how god is not the answer to anything as far as I can tell.

This isn't a God of the gaps type of argument.  (I'm starting to think that many don't understand, and do not address what is being said).

There is a gap in our knowledge and you have filled it with god. How is this not a god of the gaps argument.

What the fine tuning argument is saying; is that the evidence shows that something capable of choice and direction is responsible for what is being seen.  It also makes the notion that there is no purpose or intention behind what we see as difficult.

No it doesn't, what it says is that these are what is seen as the physics needed for life. It has nothing to say on how the physics came to be like that. This is classic god of the gaps.

"just assuming that if no one knows, god did it is the default" is a strawman, whether from ignorance, or it is intentional.

What I said is not a strawman but a factual description of what you said.

Disagreement with the inference does not make it a gaps argument.  If you want to contend the reasons of the argument, fine..... however, you cannot just label it "god of the gaps", and accurately reflect the position.
