PLEASE HELP ASAP start off by restating: Historians know about the past before there were written records by studying artifacts
The three main types of artifacts are physical, visual, and oral traditions.
Both archaelogists and historians use sources and evidence to learn about the past. Archaeologists learn about the past by studying artefacts. Historians find out about the past by studying written sources (ie what people wrote). Written sources are stored in an archive.
