What is the difference between primary sources and secondary sourses

A primary source provides direct or firsthand evidence about an event, object, person, or work of art. Primary sources include historical and legal documents, eyewitness accounts, results of experiments, statistical data, pieces of creative writing, audio and video recordings, speeches, and art objects.

Agreed ^^ Primary sources are also more reliable then Secondary sources, and should be used instead of secondary sources if you have the option
