Lots of other forms of radiometric dating can provide older dates. This is connected with the length of the half-lives involved. Carbon-14 decays down at a rate of 50% roughly every 5700. After seven or eight rounds, managing to accurately measure the minor traces left is liable to be impractical. Uranium-235, in contrast, has a half-life of 700 million years. That gives it a vastly longer range for dating. Some half-lives take billions of years whereas others are fractions of seconds.
