Hydrocarbons in Deep Earth?

Carnegie Science: "Oil and gas started out as living organisms that died, were compressed, and were heated under layers of sediments in the Earths crust. Scientists have debated for years whether some of these hydrocarbons could have been created deeper in the mantle and formed without organic matter. Now for the first time, researchers have found that ethane and heavier hydrocarbons can be synthesized under conditions of the upper mantle." There are many things hidden to the public, only the Powers That Be know about and keep secret. If you don't believe, do your own research. *FAIR USE STATEMENT:
