Geological evidence, such as zircon geochronology and high-pressure melting experiments, is used by scientists to determine the age, location, and formation conditions of the Earth's earliest continents.
The claim is specific, empirical, and falsifiable, passing Step 0 easily. Papers [1], [3], and [6] all directly discuss using geological and geochemical data (such as zircon U-Pb geochronology and experimental petrology) to determine the origins, locations, and tectonic environments of Earth's earliest continental crust. No papers contradict this premise.
