Please excuse me if I thought you were going to make the “crude comes from the deep interior” argument.
I think you might have responded to me in error.
It was Seahawkfan’s comment that you responded to in terms of close-to-the-surface crude.
I posted the wiki definition of carbon fuels primarily to Seahawkfan, and copied you just ‘cause you were in on the conversation.
I think I essentially agree with you, though I am far from well-informed on the chemistry and prehistoric chronology of fossil fuels.
