Also, radiometric dating is believed to have severe limits in terms of time...under 50,000 years.
Carbon-14 dating is one type of radiometric dating. Contrary to what creationists believe, it is not the only fom of radiometric dating.
Carbon-14 dating doesn't work well beyond 50,000 years but that is because Carbon-14 has a relatively short half-life of 5730 years.
Potassium-40 has a half-life of 1.3 billion years, and it decays into a noble gas that gets trapped inside a rock, making it ideal for dating old rocks.
Uraniam-Lead is another reliable method of dating old rocks. There's several other chains that are used.
Please know what you're talking about before spewing off ignorant creationist bull****.
