Yup. Christianity was a Johnny-come-lately that hitched its rising star to a very, very old festival, as I said in my lengthy post a few posts back.

(None of that is Jesus' fault, by the way. He didn't start Christianity...some of his followers did it in his name some time after he was gone. I also suspect he never said a word about his mother bringing him forth in a "virgin birth"...nor a number of other unusual things that his followers came up with later in order to sell their new religion more effectively. He mostly taught above loving others, not judging them, and treating others the way you would wish them to treat you...with love, kindness, generosity, and respect.)

The term "pagan" is used to describe some of those old pre-Christian religions. The "pagans" had it right...Christmas is really about the Winter Solstice, and the Winter Solstice is real, scientifically observable, verifiable, and of considerable interest to any thinking person whether or not he describles himself as "religious". That's why it has been enshrined as a celebratory time in virtually every culture that has ever existed (on this planet).
