Scientists don't just believe, they know coal is formed from ancient plants compressed in anaerobic environments. However, nobody with a knowledge of geology or paleontology believes oil is formed from dinosaurs. Oil is primarily formed from plankton and algae.
Oil sands are formed from a mixture of sand, water, clay, and bitumen - a heavy oil. Over millions of years, organic material decays and the bitumen collects in sand and silt deposits, creating oil sands. Heat and pressure further transform the bitumen into crude oil.
Oil, a complex mixture of hydrocarbons, takes millions of years to form naturally. Iron is a naturally occurring element, formed by fusion in the core of a star. As far as humans need be concerned, iron is always present and oil is formed. If you must have one faster than the other, iron is formed faster than oil.
