I remember the reason for the season, Jesus.
I know that Jesus was not born on December 25, but in September. Christmas was set on December to help all the pagans who had previously been Christians but got into the celebration of the pagan holidays, and therefore off track, to get back on track, according to the Christians.
Christmas trees have a history that originated pre Christ. There is more to this article than what I posted.

"How Christmas Trees Started
Evergreen trees (and other evergreen plants) have traditionally been used to celebrate winter festivals (pre-Christian/pagan and Christian) for thousands of years. Pre-Christian/Pagans used branches of evergreen trees to decorate their homes during the winter solstice, as it made them think of the spring to come. The Romans used Fir Trees to decorate their temples at the festival of Saturnalia. However, they were quite different to what we now think of as Christmas Trees.
Nobody is really sure when Fir trees were first used as Christmas trees. It probably began about 1000 years ago in Northern Europe.
Christmas Trees might well have started out as 'Paradise Trees' (branches or wooden frames decorated with apples). These were used in medieval German Mystery or Miracle Plays that were acted out in front of Churches during Advent and on Christmas Eve. In early church calendars of saints, 24th December was Adam and Eve's day. The Paradise Tree represented the Garden of Eden. It was often paraded around the town before the play started, as a way of advertising the play. The plays told Bible stories to people who could not read.
Christmas Trees as they came to be now started around the late 1400s into the 1500s. In what's now Germany (was the Holy Roman Empire then), the Paradise Tree had more decorations on it (sometimes communion wafers, cherries and later pastry decorations of stars, bells, angels, etc. were added) and it even got a new nickname the 'Christbaum' or 'Christ Tree'.
Some early Christmas Trees, across many parts of northern Europe, were cherry or hawthorn plants (or a branch of the plant) that were put into pots and brought inside so they would hopefully flower at Christmas time. If you couldn't afford a real plant, people made pyramids of woods and they were decorated to look like a tree with paper, apples and candles. It's possible that the wooden pyramid trees were meant to be like Paradise Trees. Sometimes they were carried around from house to house, rather than being displayed in a home.
Some trees (or at least small tops of them or branches of fir trees) were hung from the ceiling, mainly in some parts of Germany, some Slavic countries and parts of Poland. This might have been to save space or they just looked nice hanging from the rafters! (If you have lighting hooks on the ceiling, they would also be an obvious place to hang things from.)"
