Yahoo Answers fields a tough one:
“Were all bible prophesies [sic] written years after the events took place?”
Best Answer: Yes, the ‘prophecies’ in the bible are nothing that go beyond what a kid with knowledge about the world can’t predict. [I’m pretty sure he means “can” there — Ed.] Not to mention things that have always happened.”
That “best answer” is the sort of handwaving you often get from people who haven’t actually read and studied
the later books of the Old Testament. The prophets of Israel and Judah
frequently made predictions that go well beyond “things have have always
happened”.
