what does the christmas tree symbolize pagan

The Christmas tree is a symbol of the winter solstice, which is the longest night of the year and the point at which the days begin to grow longer again. This symbolizes the rebirth of the sun and the beginning of the new year. The evergreen tree is used as the symbol because it remains green throughout the winter, signifying life in the midst of death. The tree is decorated with lights, ornaments, and other decorations, which all symbolize the hope and joy that come with the new year.
