The sheer quantity of crude and the size of the oil fields should be enough to disabuse anyone that it was created by ancient life forms that were concentrated together and all died and decomposed together.
The stuff is a formative part of the earth in the same vein as rock.

The Paleozoic and Mosozoic eras when most of the shale deposits originated were almost 500,000,000 years. That’s a heck of lot of plant matter.
There's FAR more coal in the world than oil.
You can look at bituminous coal microscopically and actually see the plants that formed it.
There are no Corsi-esque imbeciles running around writing about "all coal is abiotic" - absolutely everyone accepts coal is from dead terrestrial plant matter.
Now, you can have abiotic carbon - heck, comets have carbon. Doesn't mean all the coal in the world didn't come from ancient dead plants.
The biomass of plankton is ENORMOUS - the oceans cover 75% of the earth, and the quantity of plankton is beyond belief. It's far more by weight than all the terrestrial plants and trees in the world.
The problem with oil is it will get cooked away if it's buried too deeply and too hot, or it will rise to the surface if there isn't a good cap rock system - which is why there isn't a lot more oil than there is.
