You know something else an atheist's gonna believe in??

An atheist could respond to the question of life's origins with "I don't know", or they could propose some other explanation that involves neither evolution or gods. Or they might say something in a foreign language that amounts to "I don't know" because they don't speak English...or they might not understand you if you asked in English and they didn't understand the language so you wouldn't get a meaningful answer.

Evolution is not atheism.

As has been pointed out more than once, there are other equally strong theories of speciation as evolution (e.g. some interesting quasi-Lamarckian stuff that comes out of complexity theory regarding genetic machinery). However, since the droolers fixate on evolution, that's the only one that ever gets discussed. Don't project your lack of imagination on the rest of the world.
