ano kaya ang pamana natin sa mga susunod na sibilisasyon?

Explanation:

Ang pamana ng ating kasaysayan at kultura ay magiging pundasyon ng mga susunod na sibilisasyon. Ang teknolohiya, sining, agham, at sistema ng pamahalaan na ating binuo at pinatibay ay magiging inspirasyon para sa hinaharap. Ang ating mga pagtuklas at inobasyon ay magbubukas ng mga posibilidad para sa mas mataas na antas ng kabihasnan at pambansang kaunlaran.

ang ating pamana ay hindi lamang pisikal na istraktura o teknolohiya, kundi ang kahalagahan at diwa ng ating kultura, pagkakaisa, at pagmamahalan. Ang pagpapahalaga sa edukasyon, respeto sa kalikasan, at pagtangkilik sa kasaysayan ay magbubukas ng pinto para sa mas magandang kinabukasan para sa mga susunod na sibilisasyon.
