I assume what you mean is whether we can see the back of the Moon from the earth. The answer is no, however, because of a phenomenon called lunar libration, we can see a bit more than 59 percent of the lunar surface, compared to the 50 percent we would otherwise expect for a body always showing the same fact to the Earth. As the Moon orbits the Earth, both bodies are not perfect spheres, nor is the orbit a circle with the Sun at its center. The rotation axis of the Moon oscillates by a few minutes of arc every three years, which means that from the Earth, the north and south lunar poles tilt ever so slightly towards and away from us. The net effect is that we can see 59 percent of the total lunar surface.
We can never see more than this because over billions of years the Earth and the Moon have locked themselves into a synchronous rotation/revolution mode where the Moon rotates on its axis exactly once each time it goes around the Earth every 27 days. If you take a basket ball and a tennis ball and perform this feat yourself, you will see that the same area of the tennis ball always faces the Earth, even though the entire surface of the tennis ball is rotation in space. This is one of nature's neat tricks!!
