Definition radioisotope dating
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).So if scientists wanted to measure the age of a fossil using this method, they would look for a nearby layer of igneous rock (e.g.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.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).
After examining the assumptions behind this “dating method”, and doing scientific experiments to see if this method works on rocks of an already known age, we find that “radiometric dating” isn’t all it’s cracked up to be.
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.
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.
