Query: If the "facts" aren't really facts, what is left?

A memo to the authors of this book: not everything mentioned as a fact really is so. This book repeats just about every urban myth there is. And since there are no explanations, there is no way to decide whether the rest of them are true. Ridiculously badly researched, and I don't even want to think of the harm that books like this cause at dinner parties...the wall of China is not the only human construction visible from space! Check Google Earth and see whether it is even among the easiest.Read the Straight Dope books and you'll have dozens of these corrected. With explanations.
