With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth.Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.As the lecture detailed, it is only accurate from about 62,000 years ago to 1,200 A. There is a sizable amount of time before and after that period that cannot be investigated using this method.Also, archaeologists cannot use their hands to touch the samples or smoke near them.Cosmic rays and changes in Earth’s climate can cause irregularities in the amount of Carbon-14 in the atmosphere.Humans began making an impact during the Industrial Revolution.
While an uncalibrated reading may be off by a factor of 10%-20%, calibration severely reduces that value.
In last Tuesday’s lecture, radiocarbon dating was covered briefly.
It is an essential technology that is heavily involved in archaeology and should be explored in greater depth.
If an archaeologist wanted to date a dead tree to see when humans used it to build tools, their readings would be significantly thrown off.
This is because radiocarbon dating gives the date when the tree ceased its intake of Carbon-14—not when it was being used for weapons and other instruments!
