We have to think that one through, as its so vast, what comes to mind is 'missing the forest for the trees'....
"Historical evidence suggests that Jesus, the person, was born in the springtime — but that Christian missionaries adopted Yule celebrations in order to appease and convert pagans who were deeply, spiritually attached to their own holidays. Early Christians were also fascinated by the rural, rustic pagan traditions.
“Christians of that period are quite interested in paganism,” says Philip Shaw, a researcher of early Germanic languages and Old English at Leicester University. “It’s obviously something they think is a bad thing, but it’s also something they think is worth remembering. It’s what their ancestors did.”
The two most notable pagan winter holidays were Germanic Yule and Roman Saturnalia. Christian missionaries gave these holidays a makeover and they are now known to us as Christmas."https://wearyourvoicemag.com/culture/christmas-pagan-roots-winter-holiday
The 25th of December, which we celebrate as Christmas, was the commemorative day of the birth of the sun god.
"Dies Natalis Solis Invicti means 'birthday of the unconquered sun' and was held on December 25th (when the Romans thought the Winter Solstice took place) and was the 'birthday' of the Pagan Sun god Mithra. In the pagan religion of Mithraism, the holy day was Sunday and is where get that word from!"...

Now about the Christmas tree....
When Nimrod was destroyed, he was symbolized as the tree that was cut off. To this day, his rebirth is celebrated as the new branch (Christmas tree) that sprouts from the sawed-off stump through the life-giving power of the serpent. The ancient practice of celebrating the birth of the sun god through the fir tree is found in most ancient pagan religions.
In England, Christmas is celebrated by throwing the Yule log into the fire, representing the destruction of Nimrod. The Christmas tree was then decorated, symbolizing the rebirth of the sun god.
Santa Claus has virtually replaced Jesus Christ as the main feature of Christmas. Santa rides across the skies in his reindeer-drawn chariot. He is made acceptable by his friendly appearance, but he has the same characteristics as the ancient sun deities:
The birth of Osiris, the Egyptian sun god, coincided with the day of solstice, and on this day he would ride through the heavens in his chariot. The Greek sun god Helios would ride through the sky in his sun chariot drawn by horses as depicted in the great fountain of Versailles. In the Hindu culture, the Sûrya and his charioteer Aruna rides across the sky in a horse-drawn sun chariot. In other cultures, animals such as the goat (Zeus) or the reindeer pull the chariot.
"It cannot seriously be denied that most of the features of advanced Catholic1 ritual have little
or no direct warrant in the New Testament. It is frequently urged in support of such ritual that
it can be traced in unbroken sequence back to the fourth century. “No sooner did the primitive
Church emerge from the centuries of persecution, and acquire freedom from external
repression, than it gave full and wonderful expression to its devotional spirit in elaborate and
beautiful Symbolic ways.”2 Antiquity, however, is no guarantee of apostolic authority,
especially as there is a gap of nearly three centuries between apostolic days and the
introduction of the greater part of these ritual practices into the Church. Indeed, far from our
being able to find Scriptural authority for these practices, all the available evidence on their
provenance goes to show that they were taken over into the Church from the various Mystery
cults which were so popular throughout the Roman Empire in the early centuries o£ our era.
The appeal to the Fathers cannot take the place of an appeal to the Apostles. “....
