Monte Verde in Chile's Llanquihue province, dating to about 10,500 BCE, is considered the oldest confirmed human habitation site in the Americas, while the Yana Rhinoceros Horn site in Siberia shows humans were present on the western side of Beringia as early as 25,000 BCE.
Notes on verification
Monte Verde's dating (~14,500 years BP) as the earliest widely accepted pre-Clovis site in the Americas is well corroborated by archaeological literature and reputable sources. Yana RHS dating (~30,000 years BP, consistent with ~25,000 BCE) is supported by peer-reviewed research and Smithsonian coverage. Both claims align with current scientific consensus, though debates over 'oldest' sites in the Americas continue as new finds (e.g., White Sands) emerge.
