We are constantly questioning the information that we find. I thought about this remark for a while, and had to agree with the statement. Things are more interesting if you don't know what lies ahead. Things are always coming as a surprise. Nothing in history is fixed or set.
People can find information about the past through a variety of sources.
First, everyone learns about history through school. From grammar school to college, we learn about new people, places, and events. Second, we can learn about the past through professorships, and other historical societies who are always looking for people to investigate certain events. Aside from this Professor Radding explains that the best source of information is your family. If you were to interview your family, your grandfather or grandmother, they would be able to tell you where your family came from.
