Over time, things and places get covered up and buried.
Archaeologists look for lots of different things when they begin a dig: Although a dig or excavation is one of the most important and widely known methods in archaeology, care has to be taken in its use.Archaeologists know that excavations destroy a site, so they may only sample or excavate a portion of a site leaving the rest for future researchers who may have better tools and methods. Well, garbage can tell us a lot about how people lived.There are two main reasons why archaeologists look for potential sites or decide to excavate a site: .” A midden is the term archaeologists use for a garbage dump from the past. In ancient garbage heaps archaeologists can find animal bones, shells, human excrement of glass and pottery. Just think, you may be the archaeologist's dream come true in a few thousand years! And history is what we learn about in old documents, records, letters, books and other written things.All of these provide important clues about day-to-day life. But wait, the written word is only about 5,000 years old, and in the grand scheme of things that isn't very long!So we rely on archaeologists to tell us about things that aren't written down in books.
Archaeologists can do the detective work on non-written artifacts and give us a fuller picture of the past.For example, books will usually be about famous people and we won't hear about how the average person lived.And, sometimes what people say and what they do are two totally different things.We know there is lot of history that happened before writing was invented.Also, there are a lot of things that are left out of written documents.Before an archaeologist conducts a dig, they do lots of research to determine where they might start.
