When exploring the periods for which there are no written records at all, historians have to reply on archaeological evidence.
Sources historians can use to find information include: testimony from witnesses; accounts in letters or memoirs; records from courts, businesses, churches, etc.; other books, newspapers; unwritten records; and physical remains.
Historians use historical thinking skills to critically analyze and interpret past events, identify patterns and trends, provide context to historical events, and make connections between past and present. These skills help historians to form well-supported arguments and conclusions about the significance and impact of historical events.

Historians use the evidence they find to analyze and interpret the past, draw conclusions, and form historical narratives. They evaluate the reliability and significance of the evidence to construct well-grounded arguments about historical events and trends. Critical thinking and interpretation are essential skills historians utilize to make sense of the past based on the information available.
Historians study and interpret past events by analyzing written records, primary sources, and archaeological evidence. They aim to understand the people, societies, and cultures of the past to provide insights into how history has shaped the present. Historians often conduct research, write books and articles, teach, and engage in public outreach to share their findings with a wider audience.
