The document discusses theories about the origins of the early Filipino people from three sources: the Bible, evolution theory, and legends. It describes how the first people were the Negritos who crossed land bridges 25,000 years ago. They were followed by Indonesians who arrived by boat 5,000 years ago and were more advanced farmers and fishers. The Malays arrived later 2,000 years ago and were the most advanced, living in villages with governments and arts. Legends also tell stories of early Filipinos.
