Anything older than 50,000 years must be dated on the bassi of a radioactive isotop that has a half-life longer than that of carbon-14. One such isotope is Potassium-40.

Continental crust is far older than oceanic crust.
Prokaryotes are estimated to have been around for about 3.8 billion years, while eukaryotes are thought to have evolved around 1.6 billion years ago. Therefore, prokaryotes are approximately 2.2 billion years older than eukaryotes.
Carbon-14 dating is not accurate for materials older than about 50,000 years because the half-life of carbon-14 is approximately 5,730 years. As time passes, the amount of carbon-14 decreases due to radioactive decay, resulting in lower concentrations that become challenging to measure accurately. Beyond this time frame, the remaining carbon-14 is often too minimal to provide reliable age estimates, leading to significant uncertainties in dating ancient materials.

Potassium-40 is used for dating objects older than 50,000 years because its half-life is about 1.3 billion years, allowing for dating of older materials. When potassium-40 decays to argon-40, the amount of argon-40 trapped in a sample provides a way to estimate the sample's age. This method is particularly useful for dating rocks and minerals.
