Leif forgot to tell anybody about it however. That puts him in roughly the same category as the wandering North African tribe who discovered America 35,000 years ago.

Best bet is to admit that Columbus gets credit for discovering America for the Europeans, Asians and Africans, and for discovering Europe, Asia and Africa for the Americans.

Makes him the discoverer of 4 continents and I don't think you can beat that.

If Leif forgot to tell anybody about it, then how come we know his name in this connection? The records of his doings were left, and even disseminated, but not too widely. His literary agent was none too good, that's all.
