    Well, perhaps you could just answer this for several
    of us. Isn't this the sequence of events you're
    suggesting?

    (1) Earth and moon coalesce as separate astronomical bodies
        but with the moon's composition similar to the Earth's
    (2) Some massive impact event on Earth stripped away much
        of Earth's original lithosphere---picture is found at
        http://www.cotf.edu/ete/modules/msese/earthsysflr/lithosphere.html
    (3) the carbon sequestration (http://csite.esd.ornl.gov/) altered
        the atmosphere and topsoil even more.
