Btw: In our region it is not Father Christmas or Santa Claus who brings the presents.
That is the case in North Germany.
Here in South Germany it is the Christkindl (= the Christ Child) who brings the presents.
Nobody has ever seen this Christ Child, and there are hardly any pictures or paintings.

But if these paintings are to be believed, then the Christkindl is a very beautiful teenage girl with wings, who flies through the windows on Christmas Eve around 6 o'clock pm to deliver the Christmas presents.

The Christkind is a sprite-like child, usually depicted with blond hair and angelic wings.[5] Martin Luther intended it to be a reference to the incarnation of Jesus as an infant (see Christ Child). Sometimes the Christ Child is, instead of the infant Jesus, interpreted as a specific angel bringing the presents, as it appears in some processions together with an image of little Jesus Christ. Later, the Christkind was said to make rounds delivering gifts with St. Nicholas.[6]

Children never see the Christkind in person, and parents tell them that Christkind will not come and bring presents if they are curious and try to spot it. The family enters the living room, where the Christmas tree has been put up, for the opening of presents (the Bescherung), when the parents say that they think that the Christkind who has brought the presents has now left again. In some traditions, the departure is announced by the ringing of a small bell, which the parents pretend to have heard or which is secretly done by one of the adults in the family.

Since the 1990s, the Christkind has faced increasing competition from the Weihnachtsmann, caused by the use of the American version of Santa Claus as an advertising figure.[citation needed] Many traditionalist Catholics in recent times have advocated for the tradition of the Christkind as a "beautiful means of restoring the true meaning of Christmas".[7]

Christkindl or Christkindel are diminutive versions of Christkind. Christkind and Belsnickel are also found among communities of Volga German descent in Argentina. A well-known figure is the Christkind at the Christkindlesmarkt in Nuremberg, which is represented by a young woman chosen every two years for this task.
