Actually, no one said it, since according to evolutionists, people in the bible are just myths. Not pertainent. Harry Potter may be a myth, but J K Rowling exists. So noöne, (even evolutionists) is denying that the the writer of Eccelesiastes actually existed.
Does Rowling exist? There may be a woman set up to act as the author of the Potter books, but is she really? Or is it all the carefully orchestrated work of a big corporation out to make millions? Something to contemplate.
