Scholars did not take Heyerdahl's hypothesis seriously. New Zealander Andrew Sharp proposed the accidental voyaging hypothesis in 1957, which (erroneously) argued that Oceania was too vast to have been settled by intentional voyaging so migrations must have happened by accidental drift voyages. Sharp granted that Polynesians likely settled the Pacific from
