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

]Except the multiverse a) isn't science and b) does not remove the question what fine-tuned the multiverse to be able to reliably spit out trillions of universes with varying physical laws and constants?

Hello, SteveII.  If you'd be willing, I'd appreciate some clarification from you about fine-tuning.  First, is the argument for fine-tuning attributing some kind of conscious or even human-like agency to the creation of the universe? Second, is it possible that the argument for fine-tuning could be inadvertently trying to make reality conform with a specific way of humanistic thinking rather than actually trying to understand how reality works? Also, if fine-tuning is uncertain on a universal scale, then would it be premature and somewhat short-sighted to apply this way of thinking to trillions of galaxies?
