@Fido,
we can "build" petrol substitutes from naturally occuring methane and ethylene gas.These are renewable bt, as you say, the magic ingredients are time, temperature and pressure to make all of the higher petrolem compounds. Gunga wold have us believe that complex petroleum compounds are formed renewably and quickly.
Why is it that ALL petroleum finds occur ONLY in specific geologic horizona that include ancient marine sediment deposits containing specific organisms.
Ill bet gunga cant tell us what is the youngest aged oil and gas reported
