* Candles themselves are not a natural source of light. They rely on a chemical reaction (burning wax) to produce light.

* The wax used in candles can be derived from natural sources like beeswax, soy wax, or palm wax.

* The wick in a candle is often made of natural materials like cotton or linen.

So, while the components of a candle can be natural, the process of burning and producing light is a man-made invention.

Natural light sources are things like the sun, fireflies, and bioluminescent organisms. These sources produce light through natural processes without human intervention.
