Over millions of years, Earth developed an atmosphere and hydrosphere that enabled life to start and diversify. Powered by the sun, the varied species joined stones, lava flows, and water in seeding and shaping the planet's rocky surface and oceans. Over eons, Earth evolved a complex system obeying the rules of thermodynamics that provides stability for life forms as distinct as algae, trees, microbes, and humans.
