We only see one side of the moon.

Reason:

Moon Rotates or spins on its own axis and at the same time moon revolves around Earth in a fixed orbit (path) and time taken by moon to complete on revolution around earth is nearly equal to time taken by moon to complete on rotation that is 27.3 Days so every time same face of moon appears to an observer on earth viewing moon because in completing one circle it completed one rotation also so at the end of 27.3 days it appears at same place from where it started and facing towards the earth in the same way as of earlier

The simultaneous rotation and revolution of moon around earth has been shown in the figure
