Petrol is somewhat man made. Oil is a natural resource but it must be refined in order to make gas or petrol from it.
Coke is the man made/man refined product of a naturally occurring resource (coal). Nasism is the man refined idea of natural selection.
No, coal is a natural resource.
Gasoline (USA), petrol (UK) is man-made by refining crude oil.
Petrol is extracted from crude oil. The question whether it is man-made or natural is therefore a grey area. The chemicals which make up petrol are natural, however it must be processed by man in order to obtain it in the form we use it.

No. They where here before humans. However, in the 1950s, industrial diamonds were first made by scientists in a lab, and today, you can commission or purchase a man-made diamond. Not so much with coal. It's still dug from the ground.
Leather is a man-made product produced by tanning animal skins.
MDF or medium density fiberboard is a man-made product.
Actually it's just a natural resource because it comes from the ground.
