We have the historical record of St. Nicholas, Patron Saint of children, and we have the story of how he became Santa Claus. if you don't disbelieve the record, then Santa is believable as a real person. Of course, if you don't believe the record, I have to withdraw.
And the spirit of Santa is just as real to some of us as is the spirit of Jesus and of the Great Spirit often thought of as God. And, if we believe God sends angels to help us live happier lives, Why wouldn't we believe God sends Santa? And parents? And friends and mentors?
