Earth and Moon in the Hadean epoch were pummeled by large impacts letting magma flow out. But, at the same time, some parts of Earth’s surface could have retained liquid water, allowing pre-biotic compounds to form; perhaps even life itself.

Cosmic bombardment of the early Earth repeatedly covered the planet's surface with molten rock during its earliest days, but still may have left oases of water that could have supported the evolution of life, scientists say.
