Cinematic illustration of a prehistoric Earth landscape with erupting volcanoes, a vast purple ocean, and an orange, hazy sky.

A highly detailed, scientifically inspired, and cinematic illustration of Earth 3.06–2.68 billion years ago during the mid-Archean Eon, incorporating the Purple Earth hypothesis. The scene shows a vast, dark global ocean with a distinct purple hue due to early retinal-based photosynthetic microbes dominating the planet. The shallow coastal waters are filled with purple microbial mats and stromatolites, reflecting the unique pigmentation of ancient life. The atmosphere is thick, hazy, and orange-tinted, rich in methane and ammonia, with swirling clouds and a diffuse, reddish glow from the young Sun. Small volcanic islands and proto-continents emerge from the ocean, surrounded by active volcanoes spewing lava and gases. The overall landscape is alien and dramatic, with no modern vegetation or landforms, emphasizing the primitive, hostile, and purple-tinted environment of early Earth. The lighting is dim and atmospheric, with a violet-purple glow from the microbial life and the thick, methane-rich sky. The style is hyper-realistic, scientifically accurate, and reminiscent of NASA's reconstructions of early Earth, combined with artistic interpretations of the Purple Earth hypothesis. See more
