Is divination credible?

You have to listen to what his basis is, because many fortune tellers have their own set now, some are quite accurate, and most of them are not. Before, an old woman came to our village. You said you didn't believe it, but you couldn't believe it when you saw it with your own eyes. That's because my father hasn't come to see her yet. She said that my father is three brothers and two sisters, and that my father is not his own. I wonder how he knows, and I want to point out you in one sentence.
