the fact that the moon displaces the same arc in the sky as the sun is 1 of thousands of 'coincidences' that made life possible on earth and the unique observation of the universe at this time and physical laws possible-see p52-60 of Improbable planet by Hugh Ross
the original earth had many barriers to life-including insufifcient mass/composition for plate tectonics and magnetic field necessary for life even after the lhb added 200tons of material/unit but the moon supplied the rest

cf to the earths mass the moon is 50 times larger than any other in our solar system and orbits closer than any other satellite discovered
the just right impactor hit w the just right timing mass and speed ( an improbable 4km/s)

eventually creating the right atmosphere,mass ,density,water vapor,magnetic field,long lasting radioisotopes and thus just right plate tectonics and chemicals,stabilizing earths rotation axis tilt and slowing rotation to 24 hr days necessary for life
