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

[masterofpuppets]

Sounds Great!
The reverse version of my previous thread.

The response given by theists is unsurprisingly similar to what atheists would normally say, that there just isn't any truly compelling arguments for atheism, but might give an argument they find to be more convincing than the rest.

In the end, most people are not very open to the other side, so it becomes hard to reason with the other side. Especially with religion, which is even admitted to be considered independent of critical thinking.

Except that "compelling arguments for atheism" is a nonsensical phrase, because atheism is the rejection of theistic claims that have not met their burden of proof.

In that sense, there is only one argument that needs to be made for atheism: theism sucks.
