    The missing 500 million: Cosmic bombardment melted Earth's first crust

    Geologists debate how Earth's continents formed, with some arguing that an intense asteroid bombardment 4 billion years ago melted the early crust, enabling buoyant continental crust. The oldest continental rocks date to 4.03 billion years ago, but evidence from Earth's first 500 million years is scarce.
