People already lived throughout the Americas long before Christopher Columbus crossed the Atlantic in 1492. A six-part list published by Nicholas R. Longrich in 2022 includes four chapters in Indigenous population history, a documented Norse presence in Newfoundland, and possible Polynesian contact with South America. They are not six equivalent “discoveries”: the Norse site is archaeologically dated, Polynesian contact remains uncertain, and the first four entries describe Indigenous migrations and settlement—not outsiders finding an empty continent.
What “before Columbus” means here
Columbus’s 1492 voyage became a turning point in European and global history, but it was not the beginning of human life in the Americas. The word “discovery” can obscure that distinction. In the six-part list Longrich presented in a 2022 article republished by Scroll, four entries concern Indigenous peoples’ movements and histories within the Americas. The remaining two concern transoceanic contact: a Norse settlement in Newfoundland and a possible Polynesian landfall in South America.
The evidence is not equally strong across the list. Archaeological material at L’Anse aux Meadows establishes Norse activity there in AD 1021. UNESCO describes Polynesian arrival in the Americas as possible but says it left no definite trace. The other entries are broad population-history categories; their inclusion does not make them evidence of outsiders discovering an uninhabited continent.
The six movements and contact episodes
1. The First Americans: the founding population
Longrich’s list begins with the early population whose descendants established Indigenous societies across the Americas. The exact timing and routes of the earliest settlement remain subjects of debate, so there is no single arrival date to present here as settled fact.
#1 Best Overall
The Smithsonian’s overview of Clovis points out why an often-repeated date should not be mistaken for the beginning of human presence: Clovis tools date to around 12,000 years ago, but people were in the Americas before Clovis. That figure dates a tool tradition, not the first arrival of people.
2. Na-Dene-speaking peoples: a distinct migration into Alaska
Longrich describes a separate movement into Alaska associated with Na-Dene languages and genetic evidence. Those lines of evidence can inform population history, but they do not make the people involved external “discoverers” of the Americas. The date range in Longrich’s synthesis should be treated as an estimate, not a precise, independently established date.

3. Eskimo-Aleut-speaking peoples: another Bering-region movement
The list presents Eskimo-Aleut-speaking peoples as a distinct migration from the Bering region. Its chronology and relationship to other Indigenous populations call for specialist linguistic and genetic evidence; the broad account considered here does not independently establish a precise date or resolve those relationships. This is a population-history entry, not a claim that the migrants found a vacant continent.
4. Inuit: movement across Arctic regions
Longrich also includes Inuit movement across the Arctic. This belongs to the history of Indigenous peoples in the Americas and Arctic, not to a story of a foreign arrival on an empty land. The broad six-part account does not establish a single date for this movement, so it is best described without assigning it one.
Rank #3
5. Norse settlers: a dated presence at L’Anse aux Meadows
The strongest precisely dated pre-Columbian transatlantic evidence in this list is Norse activity at L’Anse aux Meadows, in Newfoundland. A University of Groningen summary of the study reports that wood from the site contained a radiocarbon signal associated with a solar event in 992–993. Researchers counted 29 tree rings between that signal and the bark edge, establishing that the wood was cut in AD 1021.
The dating establishes Norse activity at the site in that year. It does not identify the first person to see the continent, nor does it demonstrate a lasting colony. It is evidence of Norse presence in Newfoundland centuries before Columbus, rather than proof that the Norse were the first people in the Americas.
Rank #4
6. Polynesian contact: possible, not proven
Polynesian contact with South America may have occurred before Columbus, but the evidence needs a more cautious description than the Norse archaeological case. UNESCO says Polynesian expansion may have reached the Americas but “left no definite trace.” That supports describing a possible landfall, not presenting a proven settlement or a settled account of who sailed where.
How the evidence differs
The six entries combine different kinds of historical claim. Indigenous migration histories concern the peopling and later movement of peoples in the Americas; the Norse case is a documented settlement with a dated archaeological finding; Polynesian contact remains possible but not definitively demonstrated in the UNESCO account.

- Archaeological evidence: at L’Anse aux Meadows, dated wood establishes Norse activity in AD 1021.
- Possible contact: UNESCO allows for Polynesian landfall in the Americas but says it left no definite trace.
Why Columbus is still a historical dividing line
Calling Columbus the “discoverer” of the Americas erases the people who already lived there and compresses several different histories into one European-centered label. His 1492 voyage matters because of its consequences for European expansion and global history, not because it marked the first human arrival in the continents.
Claims of other pre-Columbian voyages also need evidence appropriate to the claim. The Texas State Historical Association’s discussion of proposed voyages by figures such as Saint Brendan and the Welsh prince Madoc treats the stories as legend, while distinguishing written accounts of Chinese travelers from proof that those accounts describe real voyages to the Americas. It also notes that purported inscriptions are not accepted as unquestionable authentic evidence. Such stories should not be added to the six as established discoveries.
Sources and scope
The six-part framing comes from Nicholas R. Longrich’s 2022 article republished by Scroll. The Smithsonian’s Clovis overview supports the distinction between the Clovis tool tradition and earlier human presence. The University of Groningen’s 2021 summary reports the AD 1021 dating at L’Anse aux Meadows, while UNESCO characterizes Polynesian arrival as possible but without a definite trace. The Texas State Historical Association provides historical context for proposed voyages that lack accepted proof. The broad six-part account does not independently establish detailed dates for every Indigenous migration, so those should not be presented as settled chronology.
