The earliest inhabitants of the Philippines arrived over 22,000 years ago, as evidenced by the discovery of the oldest human fossil found in the country. Pre-Spanish Philippine society consisted of diverse ethnic groups like the Negritos, Indonesians, and Malays, who introduced various cultural traditions over subsequent centuries. The ancient Filipinos exhibited rich artistic traditions in areas like music, dance, architecture, sculpture, pottery, weaving, tattooing, and literature that were integral parts of their daily lives and cultural practices.
