“The fact that oil sample produce fossil molecules is another tell.”
Thats a contaminant which feeds on hydrocarbons. It would make as much sense to say that fish and whales are found in the ocean, proving that fish created water. Hydrocarbons can be created in the lab, by duplicating the tempurature and pressure of deep condictions. To date,, nobody has created a molecule of oil with a microorganism.
Why do you need such a convoluted answer to oil’s genesis? It’s found everywhere we seem to look in space. Carbon and Hydrogen are both the top four existing elements, and they READILY form compounds whenever they can. So why would it seem so weird that our planet is loaded with them?
Also, you might look at something else. We already have microorganisms that eat oil,, that are used in cleaning up spills. This fits neatly with the theory that the microorganisms are hungry contaminants, not the creators of oil.
So what specific microrganism demonstratably creates oil?
