Is Santa Claus real??

Some people I know say yes, some say no. If the answer is no that he isnt real then I dont understand how they can have the book called "The Flight of the Reindeer". I have it and have read it and its about the one and only man who successfully made it to the North Pole and went to Santas Village. Theres pictures of reindeer flying the the village in it. The book is hard to explain but maybe you have read it ...
