Try researching kerogen for about 5 min. Every time this comes up I roll my eyes.

I have a MSc in geology and 20+years experience as a petroleum geologist. I have spent my professional career studying petroleum basins and drilling oil wells. If you have questions, I’m happy to share to try and combat the utter ignorance.

Added bonus, my wife is a drilling and completions engineer for a big oil company. I won’t say who we work for as they are publicly traded.
