Clovis first is clearly a false theory to explain the peopling of America. We’ve known this for a long, long time... Entire careers and institutions have been built upon the Clovis first falsehood. To suggest anything else was a career ender up until very recently. So, if not Clovis... then who? I am not bought into Solutrean at all... but I am very convinced, based on evidence, that people were here far before the Clovis culture emerged or came.
