Polynesian migrations

Due to conflicting results from C14 methodology scientists have used coral tools as a dating medium in order to find when exactly the Lapita culture people left New Guinea and sailed out into the South Pacific. They came up with a date of 2838 years ago, with very low error bars. This was the age of Elijah and Elisha so what caused them migrate at that point in time – out into the ocean wide. What heavenly portent inspired them – as heavely portents played a surprising role in Polynesian tradition and myth.
