It defies common sense to say the original inhabitants of Hawaii did not drift here by chance and were not castaways.  There is no question that ancient Polynesians became highly skilled and capable navigators using non-instrument navigation, but to use such techniques to get from point A to point B, they had to know Point B existed.  The first Polynesians to arrive in Hawaiian Islands had no idea they existed, so how was it possible to use non-instrument navigation to find what they did not know existed?  Do you get my drift?
