How would you answer questions about "false" prophecies in the Old Testament?

A local pastor named Josh wrote in and shared a man in his community he's been meeting with, who is an atheist. They've been getting coffee and having lots of "lively discussions." This man pointed the pastor to a series of articles he wrote, called "the false prophecies of Isaiah, Jeremiah, and Ezekiel." In these writings, he points to some of the more obscure prophecies and posits that history nowhere mentions the fulfillment thereof. He, therefore, comes to the conclusion that all Old Testament prophets are proven false, Jesus is a fraud, and Christianity has been exposed as a sham.
