Man made
A candle is a natural light source because it is derived from natural materials such as wax and a wick.
Polythene, also known as polyethylene, is a synthetic polymer made from ethylene, a compound derived from natural gas and petroleum. It is not a natural material as it is man-made through chemical processes in industry.
It is natural but there are man-made imitations.
It can be made from natural or man made fibres.
A match is a man-made light source because it is created by the combination of specific chemical components in the match head that produce a flame when struck against a rough surface.
There are only 4 natural fabrics: cotton, wool, linen and silk. Everything else is man made,

Nothing man made is natural. The sun is a natural souce of light.
No, it's an exceedingly unnatural material. For complicated reasons, if you polymerize ethylene, you get polyethylene, but if you polymerize propylene, you get ... polyethylene again. You have to use trickery (usually in the form of a Ziegler-Natta catalyst) to get polypropylene.
because it can became with lihtning and with human.
Any heat source, whether man-made or natural.
Wax can be either natural, derived from plants and animals, or synthetic, made from petroleum products. Beeswax and paraffin wax are examples of natural waxes, while microcrystalline wax and polyethylene wax are synthetic waxes.
It is natural but there are man-made imitations.
Natural sources of these gases include volcanic eruptions, wildfires, and decomposition of organic matter. Man-made sources include burning fossil fuels, industrial processes, and deforestation. Both natural and man-made sources contribute to the levels of these gases in the atmosphere.
