This reminds me of the "universal building blocks of life" or the "standard model of biochemistry" I learned at school in the 90s. It held that all life requires water, carbon-based molecules, sunlight, and CHNOPS (carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur).

Since then, it's become clear that much life in the deep sea is anaerobic, doesn't use phosphorus, and may thrive without sunlight.

Sometimes anthropocentrism blinds us. It's a phenomenon that's quite interesting.
