i've been thought all my life that fossil fuel came from ancient trees and animals that died, etc etc..you know the drill, i'm sure they thought the same thing to us....but, somehow i just don't think so, and i'm on a quest to find the truth, for me, it just doesn't make sense.....why is it all gathered in one area??(most of oils in those arabs country), why is it so deep underground?? what's the ratio of dead body weight to oil?? say: 10 kg will roughly make 1L crude oil...., i'm not a chemical/biology student so i got no idea what's process involved in making crude oil from dead body.....nor i am a history person so that i know the world map and animal population 1 million years ago or so, can someone enlighten me??
