Petroleum geology organic origin theory

Supports for organic origin theory:-
Vast amount of organic matter is found in sedimentary rocks. Hydrogen and carbon are predominant in remains of plants and animals.
Most of the crudes have porphyrin in them that is the most essential element of life form.

If  M in porphyrin is replaced by Fe then we get hemoglobin.
If M is replaced by Mg   then we get Chlorophyll
If M is replaced with Ni or V we get a cyclic porphyrin .
Porphyrin is not stable above 200 ° C . So inorganic theory is proved faulty, as the mantel is about 33 km below the surface and average temp gradient is about 25° C/km . So the temp till we reach mantel would be about 800 ° C where porphyrin cant exist, so it shouldnt be present in the crude if it was formed inorganically.
Most of the crudes contain Nitrogen which is the basics element of amino acids that form the basis of life form.
All crudes possess the property of rotating the plane of polarised light. such a property is possessed by cholesterol which is essential component of animals and plants. The inorganic substances that possess this property are cinnaber(HgS) and quartz(SiO2)
