Here's what we do know:
* The Bible is a universal story: It tells the story of humanity's origins and God's relationship with all people, but it doesn't focus on the specific origins of different ethnic groups.
* Filipinos have a rich history: The origins of the Filipino people are complex and involve various cultural and historical influences. Archaeological evidence, linguistic studies, and historical records suggest a long and diverse history of migration and settlement in the islands.
* Cultural and religious beliefs: While Filipinos are largely Catholic, their beliefs and traditions have been influenced by various indigenous beliefs and practices.
Instead of looking for a "biblical theory," it's more helpful to understand Filipino origins through:
* Archaeological evidence: This reveals the long history of human presence in the Philippines.
* Linguistic studies: These help trace the origins of Filipino languages and their connections to other languages in Southeast Asia.
* Historical records: These documents provide insights into the arrival of different groups, their interactions, and the development of Filipino culture.
It's important to remember that the history of any people is complex and involves a variety of factors. Seeking a single "biblical theory" might oversimplify the rich tapestry of Filipino origins.
