i am truly sorry your mind is so closed to the influence of early Christian individuals who, in a effort to get Pagan converts, put together the pseudo religious holiday you celebrate today...
You're missing the point, solus. All civilizations living in sub-tropical, temperate, and frigid geographical zones celebrate a number of festivals surrounding the collection, processing, and storage of food, beginning in late summer and extending through to approximately the winter solstice. After that, if they did a good job of preparing foods and containers for long-term winter storage, and/or were good at animal husbandry and winter hunting, then they did fine. Otherwise, they did not do fine, with many sick and a lot of dead.
Regardless of when Jesus Christ was actually born, early Christians during the early to mid 4th century A.D. chose to celebrate Crīstesmæsse (Old English, meaning "Christ's Mass") on December 25. Whether then, on December 7, or January 6, the difference between which is largely due to which calendar was used, Christian writers during Constantine's reign used the pagan festival in Rome of the Dies Natalis Solis Invicti, meaning "the birthday of the Unconquered Sun", associating Christ instead as Malachi 4:2's
Sol Iustitiae, or "sun of righteousness."
All of which is beside the point. Dates do not matter. What else was celebrated on or around those dates does not matter. Whatever pagan traditions were incorporated into the Christmas (festive season) traditions does not matter.
What matters, solus, is that a little more than 2,000 years ago, the greatest gift of all, a savior to cover each and everyone's sins by faith, through Christ's sacrifice on a cross, was given by God to all of mankind so that we might be saved, both here on Earth, and for everlasting.
That's why we give presents at Christmas. It's a reflect of the gift God gave us all.
