Magic and Yetis

Mason asked me if magic was real, so we had a long conversation about why magic seems real and how magicians do tricks. I explained that the only "magic" we believe in is miracles - and that Jesus is the only one who can perform miracles. I know - lots of theology could be inserted here, but he's 6 and it's a good start. So...after my long explanation about magic he asks, "OK - but are Yetis real?".
