A scene on Earth during the Cryogenian period

A hyper-realistic depiction of Earth during the Cryogenian period: an ancient frozen landscape covered in thick glaciers and vast expanses of ice, with towering blue-white ice sheets, scattered rocky outcrops, and patches of exposed ocean water with floating sea ice. The atmosphere is cold and clear, with a pale sun casting icy reflections. No modern life forms, only primitive microbial mats visible on rocks near the water’s edge. Detailed textures, natural lighting, realistic atmospheric effects, and scientifically accurate representation of this ancient "Snowball Earth" era.
