I suppose that if I could not provide compelling evidence for belief in a particular god/gods or rational arguments for why they might exist, I could instead distract everyone by wondering whether atheists all agree on what "atheist" means. It comes off as being just a bit more sophisticated than "well you can't prove god doesn't exist."
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
