I have heard of this theory before, but could not remember where I heard it from. Thanks for posting. I do not think we have been bombarded by enough asteroids to account for all the oil in the earth though.
I think the earth is 4.6 billion years old, plenty of time to accumulate oil from meteorite impacts. I’m not suggesting that every comet and meteorite impact contributed to oil buildup on earth because they are made of different “stuff”. Take a look at the moon through binoculars and you will see craters on top of craters. The earth would look similar if we didn’t have an atmosphere and weather to erode the marks. It’s likely that earth would be more “pot marked” and struck more often because of the greater gravity this planet creates. It can “pull in” more stuff.
I don’t think we can have it both ways, oil is from organic life or it’s not.

Question: How were the layers of coal made?
Answer: A great many trees and plants, blown down by the waves and wind, became thick layers in the flood waters. They became soaked with water and sank. Then they were buried deep in the mud. Pressure crushed them together and turned them into black substance (material) called carbon. It takes 12 feet of wood to make one foot of coal. There are coal layers which are 60 feet thick. Today, there is no place on earth where coal layers are still being formed from plant life. Trees and plant life that fall on the ground decay (rot) and become part of the topsoil.
The argument is that this doesn't happen, and that these materials came from asteroids.

That's the first time I've heard that theory, but regardless of where the oil came from it's not being replaced as fast as we use it right? If there's oil in our solar system maybe we can utilize it somehow.
I have heard that water came from comets & I read recently that there is some kind of water objects bombarding us on a regular basis even today. Anyone recall that?

But I could be open to other interpretations if better evidence came up.

Well let's see,
Even if there is a inexaustable supply of abiotic oil coming from somewhere in the core and feul is free. What are we to do about global warming or is that a myth also?
Titan's upper atmosphere -- photochemical reactions similar to those that cause urban smog -- could have resulted in large amounts of liquid and solid hydrocarbons raining onto Titan's frigid surface.
2) Hydrocarbons from a particular oil field do not exhibit chemical changes as the depth of their extraction increases. But the fossils above them have constantly changing biologi-cal "signatures," which relate to their particular paleontological periods.

So.... if you are saying that all oil around the world is identical except for a few trace metals....
The North Sea oil reserves consist mainly of 'fractions' (what each different hydrocarbon is called - ie Octane and Butane are two different fractions) that are in the Octane range - that means that the oil is ideally suited for petroleum and driving cars. Brum brum brum.
The Texan oil has longer chained hydrocarbons for heavy fuel oils used to power ships. If all oils are supposed to be the same and come from the same source, why such a big difference??
Only the fact that differing plants and animals making the oils could account for this.
Crude oils and refined petroleum products consist largely of hydrocarbons, which are chemicals composed solely of hydrogen and carbon in various molecular arrangements. Crude oils contain hundreds of different hydrocarbons and other organic and inorganic substances including atoms of sulfur, nitrogen, and oxygen, as well as metals such as iron, vanadium, nickel, and chromium. Collectively, these other atoms are called heteroatoms. Certain heavy crude oils from younger geologic formations (e.g., Venezuelan crudes) contain less than 50 percent hydrocarbons and a higher proportion of organic and inorganic substances containing heteroatoms. The refining process removes many of the chemicals containing these heteroatoms. All crudes contain lighter fractions similar to gasoline as well as heavier tar or wax constituents, and may vary in consistency from a light volatile fluid to a semi-solid.
Petroleum products used for motor fuels are essentially a complex mixture of hydrocarbons. Gasolines are mixtures of hydrocarbons that contain 4 to 12 carbon atoms and have boiling points between 30 and 210 degrees Celsius. Kerosenes used for jet fuel contain hydrocarbons with 10 to 16 carbon atoms and have boiling points between 150 and 240. Diesel fuels and bunkering fuels contain hydrocarbons with higher numbers of carbon atoms and higher boiling points. In addition, diesel fuels and bunkering fuels have greater proportions of compounds containing heteroatoms.
Upon release, the hydrocarbons that are composed of fewer carbon and hydrogen atoms vaporize, leaving behind a heavier, less volatile fraction. Gasolines contain relatively high proportions of toxic and volatile hydrocarbons, such as benzene, which is known to cause cancer in humans, and hexane, which can affect the nervous system. Gasoline and kerosene releases are exceptionally hazardous due to their high flammability. Crude oils and semi-refined products, such as diesel and bunkering oils, may contain cancer-causing polycyclic aromatic hydrocarbons and other toxic substances.

One thing can be said though, the oil field are NOT filling themselves back up. If you disagree with me then rather than look at the claims of oil companies and thier purchased science and look at thier fields. Why shut down pumps and rigs if the reserve is filling back up, at least fast enough to maintain our oil supply?

If this is the case, then all of the planet in our solar system as well as the sun should have signifigant amount of hydrocrabons on them. We have yet to come across evidence for high concentrations of hydrocarbons on most of the bodies in our solar system.
