″[Just] because the boat went there 500 years ago and then left, that doesn’t give you title to property.” It was not clear what “boat” Trump was referring to.

That line is even crazier. The Norse established a settlement in 986 in Greenland. The funny part is that the Thule people, the ancestors of the Inuit arrived later then them and replaced the Dorest culture on Greenland and then later the Norse as well. Obviously there is a fairly direct linkt between the Norse and Danes.
