Don't be rude. Someday they'll discover that carbon dating has been wrong the whole time it's been used. "Funky Fundies" will have the last laugh.
No, in fact, “they” won’t. Radiocarbon dating has a range of only 50,000 years, calibration ie refinement using tree rings to find the slight fluctuations in C14 goes back perhaps 10,000, and beyond that other deposits accumulated year by year, such as coral reefs and stalactites/stalagmite reach back a bit more. Other forms of radiometric dating have other, sometimes overlapping ranges.
