Carbon dating, also known as radiocarbon dating, is a method of estimating the age of carbon-bearing materials up to 60,000 years old.

However, it is also used to determine ages of rocks, plants, trees, etc. When the sun’s rays reach them, a few of these particles turn into carbon 14 (a radioactive carbon).

A child mummy is found high in the Andes and the archaeologist says the child lived more than 2,000 years ago.

How do scientists know how old an object or human remains are?

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).Carbon combines with other elements in complex ways to form the molecules that make up our bodies.Most carbon on Earth is not radioactive, but a very small percentage is. It’s important that we allow God’s written record of history, the Bible, to guide our thinking about the past—this includes our understanding of the age of the Earth/universe How many times have you heard something like, “This animal lived 50,000 years ago”, or “This person died 20,000 years ago’?Have you ever wondered how the scientists knew the age of the bone?The carbon in their bodies at the time of their death will remain in their bodies until they decompose, or if they become fossilized, then forever. This allows scientists to look at the amount of decay in a fossil’s radioactive carbon and determine a relative date.
