The Angono Petroglyphs is one of the world’s well-preserved caves. It contained the original hand-carved writings of ancient Filipinos who lived and walked in Angono, Rizal some 3,000 years ago according to archeologists.
From what Ava and I observed when we went there last July 31 (2009), the natives already have their way of communicating with one another.
If you happen to visit the Petroglyphs, you’d see pictures of animals carved within the walls, and certain hand-writing only they could understand as the people’s way of sending a message.
Here’s the raw video clip we took there. Enjoy viewing!
