Relative and absolute dating for kids
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.
Even many archaeologists don’t think “carbon dating” is completely accurate all the time.
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.
When a volcano erupts, hot, molten rock (called “lava”) from deep inside the Earth is released. Elements are the “building-blocks” of the universe (for example, water is made from the elements hydrogen and oxygen).
But even radiometric dating does not actually directly measure the age of something (there is no substance called “age”).
It measures the amounts of certain radioactive substances.
Most people think that scientists can actually measure the ages of rocks, using a method called “radiometric” or “radioisotope” dating.
More often, rocks are “dated” by the fossils they contain, based on a pre-existing belief in evolution.
Scientists measure the proportion of carbon-14 left in the organism to determine its age.
