The Angono Petroglyphs tell us people have been living in our country for at least 5,000 years. That means as a race, we can claim we're not that young, although not that advanced as the old civilizations of the planet. There's a huge gap in our history and our scientists are continually researching to uncover how our ancestors were for 4 and a half milleniums ago, but only so much can be uncovered by the experts. It might be safe to say most of the details have been lost.
