I'm still thinking you don't have the faintest idea what you're talking about. You're rejecting the formulated opinions of thousands of PhD scientists with a 10th grade ramble about isotopes.
Did you catch the comment that's appeared several places that the isotopic analysis results are verified by simple bookkeeping? I asked you this earlier but you did not answer. If that CO2 is NOT from humans burning fossil fuels, where DID the CO2 we produced burning those fuels go to? Do you have an answer for that?
