What are the theories about the origin of the Phil?

Theories about the origin of the Philippines include the Austronesian migration theory, which suggests that the archipelago was settled by seafaring Austronesian peoples from Taiwan around 3000-1500 BCE. Another theory posits that early inhabitants may have arrived via land bridges during periods of lower sea levels. Additionally, some scholars propose that the Philippines has been influenced by various cultures through trade and migration, including Chinese, Indian, and Arab influences before Spanish colonization. These theories reflect a complex interplay of migration, trade, and cultural exchange over millennia.
