It's far from tautologous that Christ was born on Christmas day (25th December) for a number of reasons:<p>1. There are no historical references to the date in the Gospels. We can have a good guess at the year, since Luke the evangelist writes that the taxation survey bringing Mary and Joseph to Bethlehem was instigated by Caesar Augustus whilst Quirinius was governed of Syria. We could make some guesses of the season due to the shepherds looking after sheep in the open country.
There is nothing in the New Testament to suggest a specific cause to celebrate the birth of Christ, unlike his death commemoration in Luke chapter 22 for example, for which we have a much better idea of the time of year, since it was at the time of Passover, a Jewish festival which had a regular occasion based on the lunar cycle.<p>2. There are some suggestions that the Christmas festival was instigated by replacing Roman pagan festivals around that time, after the Roman Empire accepted Christianity as the state religion.<p>3. In modern times there are millions of people around the world who know very little about the story of the birth of Jesus Christ, or his significance. You'll find many places filled with pictures of Santa, reindeer, elves and other winter festival stuff... So many people could be forgiven for thinking Christmas is about Santa, not Jesus Christ.<p>As to the OP question 9, there is ample historical evidence for the existence and birth of Jesus Christ, for his death by crucifixion, and even for his resurrection from the dead (unless of course you take a priori leap of faith to believe that the material world is all that exists).<p>The significance of the birth of Jesus Christ is far more important than the date:<p>'but the angel reassured them. “Don’t be afraid!” he said. “I bring you good news that will bring great joy to all people. The Savior—yes, the Messiah, the Lord—has been born today in Bethlehem, the city of David!'
