It used to be thought that Zealandia was a young continent, but now
zircons have been found dating back 3.6 billion years -- about as old

For comparison, multicellular life has only been around for little

This is another case of where the major school of thought said NZ is not old but with some evidence it is old, just that most of the contient is
submerged below the sea.
