Christmas, Easter and Halloween rituals are all borrowed and changed from earlier Pagan beliefs.

Sorry, MrLiar, I couldn't respond back through comments so .... : Christmas: No one knows what day Jesus Christ was born on. From the biblical description, most historians believe that his birth probably occurred in September, approximately six months after Passover. One thing they agree on is that it is very unlikely that Jesus was born in December, since the bible records shepherds tending their sheep in the fields on that night. This is quite unlikely to have happened during a cold Judean winter. So why do we celebrate Christ’s birthday as Christmas, on December the 25th? The answer lies in the pagan origins of Christmas. In ancient Babylon, the feast of the Son of Isis (Goddess of Nature) was celebrated on December 25. Raucous partying, gluttonous eating and drinking, and gift-giving were traditions of this feast. In Rome, the Winter Solstice was celebrated many years before the birth of Christ. The Romans called their winter holiday Saturnalia, honoring Saturn, the God of Agriculture. In January, they observed the Kalends of January, which represented the triumph of life over death. This whole season was called Dies Natalis Invicti Solis, the Birthday of the Unconquered Sun. The festival season was marked by much merrymaking. It is in ancient Rome that the tradition of the Mummers was born. The Mummers were groups of costumed singers and dancers who traveled from house to house entertaining their neighbors. From this, the Christmas tradition of caroling was born. In northern Europe, many other traditions that we now consider part of Christian worship were begun long before the participants had ever heard of Christ. The pagans of northern Europe celebrated the their own winter solstice, known as Yule. Yule was symbolic of the pagan Sun God, Mithras, being born, and was observed on the shortest day of the year. As the Sun God grew and matured, the days became longer and warmer. It was customary to light a candle to encourage Mithras, and the sun, to reappear next year. Huge Yule logs were burned in honor of the sun. The word Yule itself means “wheel,” the wheel being a pagan symbol for the sun. Mistletoe was considered a sacred plant, and the custom of kissing under the mistletoe began as a fertility ritual. Hollyberries were thought to be a food of the gods. The tree is the one symbol that unites almost all the northern European winter solstices. Live evergreen trees were often brought into homes during the harsh winters as a reminder to inhabitants that soon their crops would grow again. Evergreen boughs were sometimes carried as totems of good luck and were often present at weddings, representing fertility. The Druids used the tree as a religious symbol, holding their sacred ceremonies while surrounding and worshipping huge trees. Easter: The word Easter itself is likely derived from Eostre, the Saxon mother goddess, whose name in turn was adapted from Eastre, an ancient word for spring. The Norse equivalent of Eostre was the goddess Ostara, whose symbols were an egg and a hare, both denoting fertility. Festivals honoring these goddesses were celebrated on or around the vernal equinox, and even today, when Easter has supposedly been Christianized, the date of the holiday falls according to rather pagan reckonings, i.e. on the Sunday following the first full moon after the vernal equinox. Rabbits, of course, are a potent symbol of fertility due to their prodigious output of young. Eggs, likewise, have always been considered representative of new life, fertility, and reincarnation. Painted eggs, thought to imitate the bright sunlight and gaily colored flowers of spring, have been used in rituals since the days of the ancient Egyptians and Babylonians. Lilies were also seen as fertility symbols because of their perceived resemblance to male genitalia. Even hot cross buns, associated with Lent, derive from the ancient Greeks and Romans, who baked “magic” wheat cakes with crosses scored in the top; two of these cakes were discovered in the ruins of Herculaneum, which was destroyed by the eruption of Vesuvius in 79 CE. The pagan celebrations most associated with modern Christian practices derive from Mediterranean cultures. The Phrygians celebrated a spring festival honoring Cybele, a fertility goddess. Cybele had a consort god named Attis, who was born of a virgin, and who died and was resurrected after three days, an occurrence commemorated sometime around the vernal equinox. Worshippers of Attis mourned the god’s death on Black Friday, then celebrated his rebirth on the following Sunday. Attis was simply the latest manifestation of earlier resurrection myths, like those of Osiris, Orpheus, Tammuz and Dionysus, who were likewise said to have been born of virgins and resurrected three days after their deaths. In areas where Christian beliefs later took hold, these already existing tales were grafted onto the story of Jesus Christ, and continue to be retold to this day. It seems that ever since the dawn of civilization, ancient peoples have always associated spring with rebirth and resurrection, with nature’s reawakening after the “death” of barren winter, and have further embodied the concept in the person of a god or goddess. And Halloween falls on the Pagan Holiday Samhain, and was changed to All Hallowed Eve followed by All Saints Day on November 1.

I don't think
