What "civilization ideas"? How did they get these ideas from an uninhabited island? Easter Island wasn't settled by Polynesians by at least 300 AD.
There is evidence of contact between Polynesian and South America. Like Polynesians having sweet potato. But not enough for visible changes of either one.
Civilization doesn't seem to spread by short contact, only close contact. Civilization is complex so a few ideas aren't enough to spread it. And it is hard for culture to accept that much change.
