It measures the amounts of certain radioactive substances.This information then has to be , based on certain beliefs.Have you ever wondered how the scientists knew the age of the bone?After all, the scientists haven’t been around that long, have they?One of these methods is based on a substance found in our bodies, plants and all living things—it’s called carbon. This makes the plant appear to have died many more years ago than it actually did (for example, the plant might appear to be, say, 3,000 years old, rather than 2,000).C in the atmosphere haven’t been constant throughout history (for instance, Noah’s Flood lowered the total amount of available carbon by burying lots of animals and plants).rock that forms from lava from a volcanic eruption)—perhaps in the rock layers above where the fossil was found, or in the layers below.When they find one, they gather a sample of the hardened lava and send it off to a laboratory to test it for radioactive elements.
The test results ranged from between 340,000 to 2.8 million years old!
When these (and other) problems are then taken into account, a scientist can interpret the result of the carbon dating within a Biblical timeframe, but even so, these results can not be used to the age of once-living things.
Most people think that scientists can actually measure the ages of rocks, using a method called “radiometric” or “radioisotope” dating.
So something that lived (and died) when the proportion of C was less than normal would appear to have died more years ago than it actually did (for example, it might give an age of 3,000 years before the present, rather than its true age of 2,000 years).
Even many archaeologists don’t think “carbon dating” is completely accurate all the time.
Imagine going for a hike in the mountains and finding a 5,000-year-old body frozen in a block of ice!
