Please explain why nearly every oil has geochemical markers from biological life and also the C12/13 ratio that indicates contact with the biosphere. I’ll accept peer review research with at least two peer reviewers and at least one Journal publication in the last decade. You might want to read my prior post I’m a petroleum geologist and a PhD geochemist / geohydrologist. Please enlighten me to a proven abiotic oil source. EVERY oil I have examined geochemically has had biomarkers EVERY SINGLE ONE. I have drilled well over a thousand wells and typed classes at least double that much in a multidecade career in petroleum geosciences.
Biomarkers are not necessarily indicators of past presence of life. How many life forms produce substances such as rubidium chloride? Never mind that your samples will never be free of contamination of biological substances anyway.
You are funny, a man with an education and a prejudiced attitude.
I don’t have that education, but I can answer your question, cross contamination. Now crawl into an oil well, take samples of the soil encapsulating an oil reservoir and prove me wrong.
Explain why oil wells that were once empty are filling up again?
Explain the arguments against abiotic oil production by planetary action. Explain how there are pools of hydrocarbon on surfaces or beneath them on several planets?
