Here’s a little religion comparison for you. The author’s information is quite dated (it’s from the 1930s), but still enlightening, I feel.

In the Babylonian and Assyrian mythologies we have the chief deities as Ishtar, Tammuz, Baal, and Astarte. In the Phrygian religion we have the Goddess Cybele and her husband Attis. Among the Greeks we have the Goddess Aphrodite and the God Adonis. The Persians had their Mithra. Adonis and Attis flourished in Syria. In the Egyptian religion was found the Goddess Isis and the God Osiris. The Semites have their Jehovah, the Mohammedans their Allah, and the Christians the Goddess Mary, the God the Father, and a son Jesus.
Christianity has divided itself into Catholicism and Protestantism; and when Protestantism gave the right of interpretation of the Bible to each individual, there were evolved such forms of Protestantism as Christian Science, Holy Rollerism, Seventh Day Adventism, Swedenborgianism, and the cults of the Doukhobors, the Shakers, the Mennonites, the Dunkards and the Salvation Army.
In the early days of the Church were seen the wrangling of sects, the incomprehensible jargon of Arians, Nestorians, Euthychians, Monotheists, Monophysites, Mariolatrists, etc. Today we behold the incomprehensible jargon of the first-mentioned sects.
Christ, born of an immaculate virgin, died for mankind, arose from the dead, and ascended into Heaven.
Buddha, who lived over 500 years before Jesus, was born of the Virgin Maya, which is the same as Mary. Maya conceived by the Holy Ghost, and thus Buddha was of the nature of God and man combined. Buddha was born on December 25, his birth was announced in the heavens by a star, and angels sang. He stood upon his feet and spoke at the moment of his birth; at five months of age he sat unsupported in the air; and at the moment of his conversion he was attacked by a legion of demons. He was visited by wise men, he was baptized, transfigured, performed miracles, rose from the dead, and on his ascension through the air to heaven, he left his footprint on a mountain in Ceylon.
The Hindu savior, Krishna, was born of a virgin 600 years before Christ. A star shone at his birth which took place in a cave. He was adored by cowherds who recognized his greatness, he performed miracles, was crucified, and is to come to judge the earth.
Christ died for mankind - so did Buddha and Krishna. Adonis, Osiris, Horus, and Tammuz, all virgin-born gods, were saviors and suffered death. Christ rose from the dead, so have Krishna and Buddha arisen from the dead and ascended into Heaven. So did Lao Kium, Zoroaster, and Mithra.
A star shone in the sky at the births of Krishna, Rama Yu, Lao Tsze, Moses, Quetzalcoatl, Ormuzd, Rama, Buddha, and others. Christ was born of a virgin, so were Krishna and Buddha. Lao Tze was also born of a virgin. Horus in Egypt was born of the Virgin Isis. Isis, with the child Horus on her knee, was worshipped centuries before the Christian era, and was appealed to under the names of "Our Lady," "Queen of Heaven," "Star of Heaven," "Star of the Sea," "Mother of God," and so forth. Hercules, Bacchus, and Perseus were gods born by mortal mothers. Zeus, father of the gods, visited Semele in the form of a thunderstorm and she gave birth, on the 25th of December, to the great savior and deliverer, Dionysis.
Mithra was born of a virgin, in a cave, on the 25th of December. He was buried in a tomb from which he rose again. He was called savior and mediator and sometimes figured as a lamb. Osiris was also said to be born about the 25th of December; he suffered, died, and was resurrected. Hercules was miraculously conceived from a divine father and was everywhere invoked as a savior. Minerva had a more remarkable birth than Eve; she sprang full-armed from the brow of Jupiter. He did this remarkable feat without even losing a rib.
The Chinese Tien, the holy one, died to save the world. In Mexico, Quetzalcoatl, the savior, was the son of Chimalman, the Virgin Queen of Heaven. He was tempted, fasted forty days, was done to death, and his second coming was eagerly looked for by the natives. The Teutonic Goddess Hertha, was a virgin, and the sacred groves of Germany contained her image with a child in her arms. The Scandinavian Goddess Frigga was a virgin who bore a son, Balder, healer and savior of mankind.
When one considers the similarity of these ancient pagan legends and beliefs with Christian traditions if one believes with Justin Martyr, then indeed the Devil must have been a very busy person to have caused these pagans to imitate for such long ages and in such widespread localities the Christian mysteries. Indeed, Edward Carpenter comments, "One has only, instead of the word 'Jesus' to read Dionysis or Krishna or Hercules or Osiris or Attis, and instead of 'Mary' to insert Semele of Devaki or Alcmene or Neith or Nona, and for Pontius Pilate to use the name of any terrestrial tyrant who comes into the corresponding story, and lo! the creed fits in all particulars into the rites and worship of a pagan God."
It is seen, therefore, that from time immemorial, man does not discover his gods, but invents them. He invents them in the light of his experience and endows them with capacities that indicate the stage of man's mental development.
