The most common method for dating artifacts and biological materials is the carbon-14 (14C) method. However, it poses a serious problem for deep-time advocates because it cannot be used for dating anything much older than 50,000 years. After that time virtually all measureable 14C should be gone. So a substantial gap exists between dating objects less than 50,000 years old and more than one million years old. The relatively new luminescence dating technique attempts to fill this gap.To read the rest, click on "Examining Thermoluminescence Dating".
In an attempt to date organic materials older than 50,000 Darwin years, secularists are trying to use the luminescence technique. This suffers from many of the same flaws as other dating methods, and has several problems of its own.
