The updated three-step methodology presents an accurate approach to cause-effect inference in impact catastrophism. It begins with (1) conclusive recognition of impact The moon-forming impact is thought to have come late in the process, because the composition of Earth’s mantle reflects only a short period of impacts by smaller bodies after The paper, by W.F.

Major impact events have significantly shaped Earth’s history, having been implicated in the formation of the Earth–Moon system, the evolutionary history of life, the origin of water on

Therefore, the apatite age represents an absolute age for fluid activity in an asteroidal setting. An impact event could have provided the heat to activate this young fluid This age is interpreted to reflect a massive collisional resetting event due to a large impact associated with the peak arrival time at the primordial asteroid belt of ejecta debris Therefore, the apatite age represents an absolute age for ﬂuid activity in an asteroidal setting. An impact event could have provided the heat to activate this young ﬂuid

Implantation might be possible if the simulation assumed a higher Theia mass, but that would produce a giant impact that is inconsistent with the Moon-forming impact (16, 17).
