There are people called excavators and they dig far into the earth to find old artifacts(or items). When they find evidence, they will make a hypothesis(prediction) of what the item was used for and how it was used.
by using reading the 'fossil checklist.' Fossils from micro organism, vegetation, fungi and then ultimately animals are preserved in diverse sedimentary rock layers and dispensed around the worldwide. Scientists can see what varieties of 'previous life' known by relationship strategies. Carbon may well be used for this by using gazing the quantity of Carbon 14, which decays to Nitrogen 14 by beta decay. Carbon 14 has a a million/2 life of 5370 years. So by using gazing the quantity of Carbon 14 and Nitrogen including the a million/2 life, the quite age would be formulated! in case you opt to google something to study greater put in those words: the fossil checklist cambrian explosion of life carbon 14 relationship mass extinctions or maybe purely fossils
