It all depends on having a source of low-entropy energy. For Earth that would be sunlight. Other ingredients are needed, naturally, namely: an environment full of the things that are needed to turn low-entropy sunlight into local low-entropy systems that externalize their entropy production (life). First we have photosynthetic, and then we have all the lifeforms that depend on them. (Yes, there's also chemosynthetic lifeforms that use other a different path to locally reducing entropy.)
