Many people will swear that store merchants did when we observe cash registers singing and shopping malls filling up with happy shoppers during the days before Christmas. However, Christmas is not a physical invention - it is both an old tradition and a Christian holiday celebrating the birth of Christ. Many physical inventions have been created to aid with Christmas festivities that you can research the history about including: candy canes, electric Christmas lights (invented by a teenager), artificial Christmas trees, and snowmen.

Who Invented
The existance of jesus has been proven beyond reasonable pshychological doubt.the existance of christmast is just a commercial tactic,
Leonard your comment is laughable. There is hardly any unbiased proof that there ever existed a Jesus of the kind that is described in the bible or koran. Christmas was celebrated for about 700 years before the Jew, Jesus Christ, was even said to be born, where people decorated trees, exchanged gifts and had a week-long feast. Christianity successively stole this holiday and claimed it for their self. It’s one of many times that religion has tried to erase history and rewrite it in their benefit.
