Earth is probably NOT typical
Given the moon's existance we must assume that the Earth is NOT a typical 'terrestrial' planet in a habitable zone. Something less than common happened here. No Copernican principle. What the consequences were for complex animal life's origin making it more likely or deferring it for a gigayear or worse, we don't know. We DO know that the Earth has been 'relatively' stable temperature wise for life over a few gigayears as long as relatively includes swings between massive ice caps to plus 110 degree temperatures.
