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

[RoadRunner79]

Right.  No conflict with science at all.

Steve II already provided the standard dodge to this and every other perfectly good example you can provide: the cause is allegedly supernatural and therefore outside the purview of scientific inquiry and judgement.

Of course, it's all bullshit designed to avoid admitting one's religious stories are silly and antiquated. Reasoning with such people is largely a waste of time.

We can look at your reasoning if you like.  I do hope it is better than the ad hominem seen so far!

Also, if science makes a naturalistic explanation of the evidence improbable, I don't think that helps your case.  It also doesn't show that it is false.
