Life would be different if there was no Moon. There would be no eclipses, well Venus does get between the Sun and Earth, but just not the same. The nights would be much darker, we would see more looking up in the night sky. The tides, would be very small with the Sun causing them. With no tides caused by the Moon, there would be no tidal friction, which would mean the Earth would rotate faster. That would provide us with much shorter days, 6 to 8 hours long. The Earth's axial tilt would change greatly, which in turn would have a major effect on weather. With these and other effects on the Earth without the Moon, life would evolve differently. But thankfully we do have the Moon looking after us and can enjoy chocolate on the only planet that it grows on, as far as we know.
