why do we put christmas trees up at christmas

"Well, I think the main reason is because they're beautiful and they make us feel happy and festive. But there are also a lot of stories and traditions surrounding Christmas trees. For example, some people believe that the evergreen tree symbolizes eternal life and hope. And some people believe that the Christmas tree is a reminder of the birth of Jesus Christ. Whatever the reason, I think it's safe to say that Christmas trees are a big part of what makes Christmas so special."
