Our earliest reliable records of this planet, some 3.5 billion years ago, contain distinctive evidence of microbial fossils, including distinctive shapes that correlate to the sizes and shapes of current prokaryotes, as well as carbon-ratios distinctive to life as we know it (Schopf 1993, Schopf et al. 2017). Many analyses have pushed our confidence in life’s earlier origin significantly further back, suggesting that basically as soon as Earth was not molten, it was filled with life (Pearce et al. 2018, Lineweaver 2020). How life started and why it started so quickly remains one of the most pressing open questions in science.
