Fire gets it’s energy from fuel+oxygen. Most life does too. Plants (and other photosynthetic organisms) can also get energy from light but that requires you to sit in the sun doing not much for a long time. There’s also chemosynthesis, where energy is obtained from a chemical reaction, but that’s usually not nearly as powerful as oxidation.
Put another way, a car with NOS is way faster and more powerful than one without. So too is life that uses oxygen more powerful than life that doesn’t.
Even py.game would be better at this point…
