Because the earth is facing away from the sun, making the earth in between us and the sun.
This is more of a puzzling question than you might think, since the beginning of time astronomers have been wondering why the night sky is not as bright as the noonday sun, as there are billions of stars in the sky to light it all up. This subject was popularised by German astronomer Heinrich Wilhelm Olbers in the 19th Century and is now known as Olbers Paradox. Since Edwin Hubble's time, astronomers have calculated that the universe must be expanding, and is not infinitely old so the light from very distant stars can never reach the Earth, meaning that the night sky will be dark.
