This... this is news to me. Always been taught that its from old organic matters trapped down in the earth, not as part of the Earth's natural process. Hence "finite" in numbers.

EDIT:

So if oil is part of Earth's natural process, then by the earliest of time the organic building blocks of life is already abundant on Earth. Then you get maybe a foreign interplanetary microorganism to kickstart the life process.

I guess if we can find another planet with similar geological process and find oil, we would finally recognize oil as part of that process or we declare there was once life on that planet ol
