True by verification and replication of radiometric dating techniques for volcanic eruptions above and below dinosaur fossils. True by a convergence of evidence from a wide range of phenomena, such as the cosmic microwave background, the abundance of light elements (such as hydrogen and helium), the distribution of galaxies, the large-scale structure of the cosmos, the redshift of most galaxies and the expansion of space.

Dating is not necessary to demonstrate that evolution is a fact.

Chronological sequence is all that is really required.

So by measuring carbon 14 levels in an organism that died long ago, researchers can figure out when it died.
