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.
