I cannot recommend books that are so full of errors that they will badly mislead and miseducate the reader, and that commit so many mistakes that I have to substantially and extensively correct them.
Did Jesus Exist? ultimately misinforms more than it informs, and that actually makes it worse than bad. Like the worst of mythicist literature, you will come away after reading it with more false information in your head than true, and that makes my job as a historian harder, because now I have to fix everything he screwed up. This is why I don’t recommend anyone ever read bad mythicist literature, because it will only fill your head with nonsense that I will have to work harder to correct. Ehrman’s book ironically does much the same thing.
Therefore, it officially sucks.
