Other methods such as Potassium-argon dating and Isochron dating are based on faulty assumptions and so unreliable as to be useless.Many atoms (or elements) exist as numerous varieties called isotopes, some of which are radioactive, meaning they decay over time by losing particles.Thus, if you are a scientist, based on the extensive work calibrating radiocarbon dating, the process largely amounts to determining what kind of sample you have and measuring the carbon-14 to carbon-12 ratio.Then you look through the calibration table for that measurement and read off the proper age.

Uniformitarian geologists consider this form of dating strong evidence that the Earth is billions of years old.

Two excellent examples include tree rings and lake varves.

Because of variations in the rate of growth (usually caused by seasons), tree rings provide an excellent way to generate a “fully-anchored” chronology of growth that extends as far back as 12,000 years.

Obviously the details are slightly more complicated but the concept is simple.

If you trust your ability to read a tax table to compute your taxes, utilize an ear thermometer to take a temperature, or even use a ruler to measure a length, you should also trust dates found using radiocarbon dating.
