Earth during the Tonian period

A hyper-realistic depiction of Earth during the Tonian period, 1 billion years ago; vast ancient oceans dominate the planet, with scarce volcanic islands and primitive supercontinents under a dramatic sky filled with early atmospheric haze. No plants, animals, or advanced life—just barren rocky land, crystal-clear water, and subtle hints of early microbial mats along shorelines. Pale sunlight filters through a primordial atmosphere, evoking a sense of ancient, untouched Earth.
