There is no such a thing as a fossil fuel
There are such things as fossils. Pretty sure they aren’t related to fuel either.
Supposedly early oil magnates (with the help of a compliant media) planted the false notion that petroleum is a product of decomposing plants and animals.
It was done in order to create a belief that the deposits of petroleum were limited thereby justifying higher prices.
Even today, after pumping petroleum out of the ground for 160 years, supposedly educated people still believe in that foolish and fallacious notion.
