Phew! I feel better already.
The hypothesis of abiogenic petroleum origin holds that most petroleum was formed from deep carbon deposits, perhaps deposits dating to the accretion of the Earth. The ubiquity of hydrocarbons in the solar system is taken as evidence that there may be a great deal more petroleum on Earth than commonly thought, and that material may exist at depth in the Earth’s crust and mantle. Adherents to the abiogenic hypothesis often downplay or dismiss altogether the more widely held view that petroleum is a fossil fuel produced from the buried remains of ancient living organisms.
