Short summary
What was Earth like when young? Under what conditions did bacteria spread? We studied some of the best-preserved, oldest rocks in South Africa. Layers there are about vertical; we drilled sideways. Sedimentary strata from eight boreholes showed that they had been deposited in rivers, sandy shorelines, tidal flats, estuaries, and the ocean. Some have well-preserved remnants of microbes. We will learn how life was established on a planet which would appear very inhospitable to us nowadays.
