Earth during the Ectasian period

A highly realistic depiction of Earth during the Ectasian period, approximately 1.4 billion years ago: ancient barren continents with minimal land vegetation, surrounded by vast, shallow primordial oceans, under a hazy, reddish sky rich in atmospheric gases. No animals or complex plants, with only microbial mats at the edges of water and rocky outcrops, capturing the early geological formations and a distant, faint sun, in a detailed, ultra-realistic style.
