Archaeologists look for evidence about early people by excavating sites, analyzing artifacts and ecofacts, and using scientific techniques like radiocarbon dating to determine the age of remains. They also study the environmental context of the site to understand how early people lived and interacted with their surroundings. By combining different sources of evidence, archaeologists can reconstruct the lives and cultures of early people.

Lawyers seldom look for evidence. The police investigate the crime and collect all the evidence. The attorney may find additional evidence after talking to their client, such things as video or transactions that can provide an alibi or other witnesses. In those cases they often hire a private investigator.
