Fossil fuels are organic fuels that we use such as oil, coal, and natural gas. Fuels such as coal were formed during Noah's Flood. Other fossil fuels such as oil and natural gas were formed as Noah's Flood continued to heat the already laid coal beds. Fossil fuels are very important to society. They play a major role in the economy as it coal and the mining of coal bring in a lot of money and much of the things we own rely upon fossil fuels.  The use of fossil fuels account for more than 85% of the total US energy use.
Deposits of Oil are normally located in sedimentary rocks. These sediment layers were formed as rocks such as silt, sand, and clay grains were washed away and carried by water to a new location where they were then deposited in layers. These layers dried up and the sediment grains where bound together by a natural cement that previously formed from the chemicals that where in the water. Vast amounts of oil are found trapped underground is porous sedimentary rock. The oil amasses together in the the small spaces between the sediment grains. Oil is not formed in sedimentary rock but moves through the layers of rock until it becomes trapped. Oil is said to have formed organically from the fossilized remains of plants and animal but there are those who say it could have been created inorganically. The chemical makeup of oil shows that it is an organic substance. The chemical, porphyrin, is found in animal blood, plants, and also oil. Porphyrins are, "Any of various organic compounds containing four pyrrole rings, occurring universally in protoplasm, and functioning as a metal-binding cofactor in hemoglobin, chlorophyll, and certain enzymes." Crude oil is said to form from plants and large beds of coals but because of the presence of porphyrins in the chemical makeup of oil there is a chance that crude oil can be extracted from the fossilized remains of animals. The remains of slaughterhouse animals can be transformed into high-quality oil in less than two hours. They can be formed rather quickly if made from the proper organic materials. The source of oil comes from the many forests of trees and the vast numbers of diatoms that inhabited the pre-Flood world. When God sent the Flood the trees were washed away and buried with other large groups of plant remains. These large groups of buried plants became the coal beds that we have now and as the Flood continued to happen these coal beds were buried even further down into the earth. The temperatures of these coal beds increased and crude oil and natural gases were created. The oil began to disperse throughout the porous sedimentary rock until trapped and are now the oil beds and natural gas deposits that we have now. 
Coal beds were formed about 4,500 years ago during Noah's Flood. They are a result of the plants that were washed away by Noah's flood and buried together quickly.  The plants that form coal were gathered, changed, and packed together rapidly. Two theories exist on how coal was formed. One is that the plants that make up coal were all gathered in big freshwater swamps or peat bogs and left there to form over thousands of years. This is one of the most popular theories that many uninformitarian geologists cling to. The other theory is called the allochthonous theory and this theory puts forth the idea that plants that make up coal were quickly fathered and deposited together under the conditions that Noah's Flood brought. Fossils of marine animals are very common to find in coal. The mix of marine animal fossils and fossils of non marine plants hints that these elements were being taken from different areas and then buried together. Some of the plant fossils found in coal do not completely support the allochthonous theory. Fossils of plants such as the lycopod tree and the giant fern, which are usually found in the coal collected in Pennsylvania, are tolerable to a swampy environment and may be shown to prove the uniformitarian theory of how coal was formed. Although there are fossils of plants in coal that are known not to inhabit swamps. The plant fossils in coal are mostly used to point out whether it was formed in a tropical or subtropical climate. There are three theories of how peat changes into coal. In one of the theories the amount of time that the peat has to form into coal is the main part of the theory. The second theory has the amount of pressure applied as its main focus. The third theory puts forth the idea that temperature plays the most important part in coalification. This is the most popular theory and it has been proven that coal does not need millions of years to form but can form in a short time by rapid heating. 
There are many scientists believe that natural gas and other fossil fuels were formed organically. Some scientists claim that it might have formed during the melting of rocks deep within the earth. There is more evidence that shows it being formed organically rather than inorganically from the melting of rocks. Also the coal beds there were laid and buried by the Flood formed a lot of natural gas because their temperatures were increased due to the progressing flood. The oil and natural gas formed from these coal beds moved through the sedimentary rock until they became ensnared and formed the natural gas and oil pools we have today. 
Fossil fuels are used for many things such as oil for cars and coal mining brings in a lot of money. Natural gas is a component of the natural based fertilizer that different crops grow in. Fossil fuels are apart of everyday living and much of our industries are dependent upon fossil fuels. Coal can be used in power plants to create electricity and many automobiles require oil to function correctly. Heating and cooling systems also electricity that is often generated by fossil fuels.
