Like any other plant today but the animals may be slightly different
No one knows how long it takes, but the current supplies of oil apparently date from organisms that lived hundreds of millions of years ago.
A long time ago
the fossil fuel created is coal
"Fossil fuels" refers to fuels, such as carbon and petroleum, that are generally believed to originate as fossils.
organic matter
Fossil fuels are formed by plant and animal matter that decays differently under immense pressure and large periods of time deep in the earth's crust. As long as there have been plants and animals (subtracting the perhaps million years it takes to actually form the fuel), there have been fossil fuels. In this way, fossil fuels ARE renewable, though it takes a very, very long time. As long as things continue to die and be buried and potentially, to fossilize or decay, there will be fossil fuels, though there is an argument about how long sufficient quantities of these fuels will last.
Fossil fuels are made up of dead animals and plants and over a long period of time, the decayed plants and animal remains are compressed together with dirt.Over millions of years they will form coal.

The sun's radiation grew plants (photosynthesis)Animals ate the plantsPlants and animals died and were crushed underground for 300 million years, turning into fossil fuels (coal, oil and natural gas)We dig them up and burn them, releasing that long lost energy from the sun! (As well as the long lost carbon dioxide!) nnnn
Fossil Fuels are created when the remains of plants and creatures are put under extreme pressure for extremely long periods of time. There Isn't an infinite amount of vegetation and creatures that lived that long ago, therefore there isn't an infinite amount of Fossil Fuels.
It's wrong to say this because it is inaccurate. Fossil fuels are stores of potential energy which can be converted (through combustion) into heat energy. Light energy is the energy that gives off light, but fossil fuels do not give off light.
Fossil fuels come from plants and microscopic organisms, which long ago died and were buried in the earth and slowly transformed into coal, oil, and gas. These plants and microorganisms once, millions of years ago, got their energy from the sun. Thus, all fossil fuels received some solar energy.
I will rephrase your question- Is the supply of fossil fuels sustainable? The answer is no. In the long run, we will have less and less fossil fuels. Fossil fuels are referred to as non-renewable fuels, which are taken from the earth's resources and used.
