Recent archaeological evidence suggests that people may have been on the North American continent 14,700 years ago.

Confirmed by multiple independent outlets reporting on peer-reviewed 2020 Nature study (Ardelean et al.) using Bayesian age-modeling of Chiquihuite Cave and other sites. Claim is conservatively phrased with 'may have been,' consistent with ongoing scientific debate about earliest human presence in the Americas.
