This is only true to a point. Who knows more than the oil geologists who primarily work for oil companies. Where else would they work? There is no concensus on when the peak will be reached but based on the information I have read most oil geologists believe between 2007 and 2010 is most probable. The later dates like 2026 to 2037 generally come when one adds in the work of economists who are plotting economic data to come up with a date. You have to decide for yourself whether you think economists or geologists are better at discovering oil reserves or estimating the size of existing reserves with the data they have. What seems funny to me is trusting economists over geologists when it comes to finding oil.
While it is true no one can know for certain until it has passed the smart money is on a date before 2010 in my opinion.
