The presenter argues that Clovis-first held for much of about 40 years, with consensus shifting after roughly 30. The presenter says excavated evidence from Monte Verde, Chile, was shown to Clovis deniers and that they accepted pre-Clovis cultures were possible. The presenter notes that evidence against Clovis-first had been accumulating for about a century. The video compares this timeline with germ theory, which the presenter says took 30–40 years to win after specific bacteria were linked to anthrax, TB and cholera. The presenter’s point is that real science corrected itself quickly once hard, replicable evidence appeared, whereas archaeological consensus changed only after physical evidence could no longer be dismissed. 🧪🌎
