Polytheists are people who believe in more than one god. As most religions were polytheistic prior to missionaries spreading monotheism, and all cultures have religion, polytheism would reasonably be expected to have existed since prehistoric times. Further, when explorers met prehistoric cultures (cultures that did not yet have written records), many of them were polytheistic.
Scholars learn about prehistoric humans through various methods such as archaeological excavations, analysis of ancient artifacts, examination of human fossils, and studying ancient DNA. By piecing together evidence from different sources, scholars can reconstruct the lifestyles, cultures, migrations, and interactions of prehistoric humans.
