摘要

Now we understand that during its formation our planet got a steam atmosphere. Presumably during the cooling phase all the water vapor in the atmosphere would condense and form the ocean (we will talk about that later in the book). This steam atmosphere should have been substituted by a primordial atmosphere originated probably by the degassing of impact planetesinals.
