Primary sources help us learn about people in the past because you are learning about events that occurred from people that were there to actually witness it. You get first-hand information passed to you whether it's via your grandparents, a journal, or a letter. From primary sources you can also learn about the ways people lives were. You are informed about their culture, religion, foods, and clothing. Differing from secondary sources, you are not reading or listening to information about the past, or even present, that is biased and has edited or opinionated information included.
