Imagine digging into cave dirt and pulling out a 20,000-year-old mammoth bone needle.
Is holding that actual needle the same thing as reading a chapter about Ice Age clothing in your school textbook?
To solve mysteries about the ancient world, historians sort every piece of information into two groups: primary sources and secondary sources.
What makes a clue belong to one group instead of the other?

Clues from the Past: Primary Sources

A primary source is direct, first-hand evidence created during the exact time period you are studying.
Because ancient people rarely left written letters or diaries, their primary sources are usually artifacts — objects made or used by humans, such as stone hand axes, cave paintings, or campfire ashes.
Primary artifacts give us original physical proof, but who gathers all those scattered clues and turns them into a story you can understand?

Looking Back: Secondary Sources

A secondary source is information created later by someone who did not witness or live through the event first-hand.
Secondary sources analyze, interpret, and combine many primary clues — think of your history textbook, an educational YouTube video, or a modern encyclopedia entry.
