The force of gravity makes sure that it does not float away from the earth and makes it revolve around it. The fact that the moon does not crash into the earth is because of the tangential velocity of the moon, in a direction perpendicular to the direction of the force. In fact, the revolution of the moon around the earth is due to two causes: the tangential motion and the constant falling towards the earth.
