The search for exoplanetary life must encompass the complex geological processes reflected in an exoplanets atmosphere, or we risk reporting false positive and false negative detections. To do this, we must nurture the nascent discipline of exogeoscience to fully integrate astronomers, astrophysicists, geoscientists, oceanographers, atmospheric chemists and biologists. Increased funding for interdisciplinary research programs, supporting existing and future multidisciplinary research nodes, and developing research incubators is key to transforming true exogeoscience from an aspiration to a reality.
