Some oil is found BELOW all of the fossil layers. Oil is less dense than the surrounding rock …. so how did it get down there, unless it …. bubbled up from deep in the earth’s mantle ?
Oil, natural gas, and coal can be found in or very near earthquake faults or volcanic vents. This further supports the idea that oil is not a fossil fuel. Coal is fossils that have trapped extra carbon; the natural gas can permeate up through the coal.

Coal mines have natural gas fires; earthquakes are often preceded by weird clouds.
