What have we invented?

WHAT have we invented as a nation?
We did invent sail canoes that navigated our seas using natural stellar systems, we invented the longest and biggest Gogodala house, the Abelams built the famous haus tambaran depicted on Parliament House today, Lakatoi by Papuans, Koiari tree house, Kuk valley fossils of our earliest forms of agriculture only to be beaten by yet recent findings in Goilala that proved agriculture existed here 60,000 years ago.
Our age of civilisation and invention was proven by science.
We ask what now, what went wrong in pre first-contact era? What is happening to us now in this time of mix culture, money, space and digital age?
