Title: How four billion years of Earth history may help us find life on exoplanets

Abstract: Life and life-sustaining environments, including oceans, have existed on a dynamic Earth for more than four billion years. Each of our many past planetary states was associated with a particular atmospheric composition, and those atmospheres contained gases that were produced by Earth's early life. Using ancient Earth to understand when and how these biosignature gases accumulated is allowing us to select targets and techniques for exploring the many Earth-like planets beyond our solar system. And a deep dive into Earth's earliest chapters is providing an environmental context for life beginnings.
