I’ll go with the low-hanging fruit: Mein Kampf. I’ve read it, cover to cover. As a piece of propaganda, it’s good. As an example of good writing? Absolutely not (though I will admit I have only read it in translation). Oh, and the whole fascist, racist, and generally shitty worldview of the author that he infuses into the text. And the fact that the author is literally Hitler. You 5-star that book? You’re a Nazi. Period. And as a Jewish person, I don’t look too kindly on them.
Consider the San Diego Skulls discovered by Malcolm J Rogers. When judging the skulls antiquity, George F. Carter (previously a Curator of Anthropology at the San Diego Museum and Senior Geologist at the Texas A and M University) judged them to be 40,000 years old. There are plenty of other artifacts and remains that have been dated well before the time window in which the Land Bridge theory would allow.
