A detailed depiction of Earth 2 billion years ago, featuring a barren, rocky landscape with no vegetation or animal life. The terrain includes vast stretches of water with greenish, film-like layers of cyanobacteria floating on the surface, illuminated by a dimmer, slightly cooler Sun in the sky. Sparse ice patches are scattered, and volcanic activity is evident with erupting volcanoes emitting ash and lava flows in the distance. The atmosphere appears hazy, with low oxygen levels, reflecting a primitive and alien world at the halfway point of Earth's age.
