This event may well have stripped away any previous atmosphere and oceans; in this case gases and water from comet impacts may have contributed to their replacement, although outgassing from volcanoes on Earth would have supplied at least half.
Este evento puido ter eliminado calquera resto de océano ou atmosfera previos; neste caso os gases e a auga dos impactos de cometas puideron contribuír á súa rexeneración, xunto coa desgasificación volcánica do interior da Terra, que subministrou a outra metade dos gases.
