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

I've tried to get him back on topic... he just runs away from it....   I'm done with him any way.
Some may think that calling people names, and putting them down is winning,.., I don't feel that way

You're completely missing the point. You just want to keep on talking about how Brian is "trolling" and "not on topic" when it seems like YOU don't understand the point he's making. You're essentially committing an ad hominem fallacy.

Gods are just nonsense. They can't all be right, but they can all be wrong. It doesn't take more than a few minutes to see how deities were all just made up by humans during a time when they felt scared and lonely, or even worse, when they wanted to control other people. Either that or your specific god actually exists. Why are you correct when a Hindu is wrong? A Hindu can point out as many absurdities (probably more) in your religion than you can point out in his.

No, but his point is bad logic to begin with, and doesn't effect what was being discussed in the slightest.  No one is saying that this shows evidence for a specific god, but some general descriptions, that are normally attributed to something that we would call god.  Just because the gunpowder residue on the suspect's hands, don't show that he did shoot the victim, we don't throw that evidence out.  Or for a closer analogy, just because the evidence shows that it was murder, but doesn't point to a specific person, you don't ignore the evidence, and declare natural causes, as the reason for the death.  Similarly, I would laugh at a defense attorney, who gave the reason, that you reject all the other billions of people on the planet for committing the crime, I just ask you to reject one more in his client.  It doesn't follow.  

And yet again, if you look at a number of the fallacies, you will notice a pattern, that they do not effect the logic or reasons, given.   That is why they are fallacious.
