I remember seeing a meme about what alien life might be like and they say "what do you mean all life on Earth breathes rocket fuel???"

    I get these stories as a way of pointing out the inherant absurditity in a lot of every day things...

    ...but also... life requires energy. Something's gotta keep the metabolism going. Oxygen is both highly reactive and significantly more abundant than any of its heavier counterparts further down the column. If there is life out there with a metabolic rate anywhere approaching our own, it would be weird if it didn't use oxygen.
