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.
