A sine wave is “natural” because it’s the graph of many natural phenomena. E.g. A weight on a spring bouncing up and down. A pendulum. A water wave. A sound (pressure) wave.

These all have the property that the restoring force is linearly proportional to the displacement. Sinusoidal movement is the result.
