Of course, the best method is to check the account of a reliable eyewitness, if one is available. Since it is the written Word of God, we can trust it to tell us the truth about the past.
Carefully studying the Biblical record, we find that the universe has an age of around 6,000 years, and that a world-changing, global Flood occurred about 4,300 years ago.
You might be wondering how we know that the Iceman is more than 5,000 years old. Carbon dating is a way of telling the age of a once living thing by measuring the amount of carbon inside of it.
Carbon dating was such an important discovery that American scientist Willard Libby won the top science award called the Nobel Prize for discovering it.
Those who don’t accept the Biblical account of history look for other ways to discover the age of things.
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).
In 1991, this adventure actually happened to a couple that was walking in the mountains of Europe.
When scientists chipped the Iceman out of the block of ice he was found in, they tested his body to see how many carbon-14 atoms were remaining, which told them his age.
Do you know what you have in common with a tree and a dog? Carbon is an element that is found in every living thing on planet Earth. One form of carbon inside living things is called carbon-14.
Carbon-14 is a radioactive form of carbon, which sounds scary, but it's not dangerous, it just means that it's not stable, so after an organism dies, carbon-14 decays or goes away.
Carbon is one of the most important elements to life on planet Earth.
It forms more compounds than any other element and forms the basis to all plant and animal life.
