Leif Erikson
Leif Erikson or Leif Ericson ( 970 – c. 1020) was a Norse explorer from Iceland. He was the first known European to have set foot on continental North America (excluding Greenland), before Christopher Columbus. According to the Sagas of Icelanders, he established a Norse settlement at Vinland, tentatively identified with the Norse L'Anse aux Meadows on the northern tip of Newfoundland in modern-day Canada. Later archaeological evidence suggests that Vinland may have been the areas around the Gulf of St. Lawrence and that the L'Anse aux Meadows site was a ship repair station.
Jeffrey Goodman
Goodman claims that the fossils in North America are "twice as old as the oldest fully modern skull from europe". In his work he attempted to show that the American Indians were not only the first Americans but were the first humans on earth. Goodman allows that hominids did appear in Asia and Africa, though homo sapiens are completely American in origin according to his theory. Goodman's theory has been criticised as his explanation of the relationship between hominids and humans was vaguely discussed. However Goodman in a later book addressed the issue in "The Genesis Mystery: the Sudden Appearance of Man" (1983) in which he criticised natural selection and advocated a type of spiritual evolution by claiming that archaeological findings verify an unbridgeable gap between modern man and the last "pre-man" creature and advocates spiritual intervention as the explanation for the "sudden appearance" of modern man. According to Michael Anthony Corey: Goodman "appeals to an intervening supernatural force, which would have manifested itself entirely through a "natural" series of evolutionary processes".
