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?Of all the carbon in the world only a very small amount is radioactive. Plants are designed to absorb carbon dioxide (what you and I breathe out --. How Carbon Dating works Carbon dating is one method scientists use to measure the ages of objects which were alive at some time in the past. In our atmosphere there are particles of carbon, when rays from the sun hit them it turns a few of them into carbon 14 (a radioactive carbon). 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).
More often, rocks are “dated” by the fossils they contain, based on a pre-existing belief in evolution.To test this method, some scientists gathered samples from hardened lava at Mount St Helens, which erupted most recently in the early 1980s.The samples, which came from rocks that formed between 19, were sent to a lab and were “dated” using the potassium-argon (K-Ar) method.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.
