Christians: Does it bother you that the story of jesus is the sames as many other preceding "gods"?

The jesus story - born of a virgin on December 25th, had a star over the place of his birth, was visited by three kings or magi, was a teacher at the age of twelve, had 12 followers, was called the lamb of god, christ, son of man, etc, performed miracles, was dead for three days, and was resurrected - is a very common mythical story that was told thousands of years before jesus was supposedly born. Many "gods" have this exact same story (or one very similar) such as Horus (Egyptian god) in 3000BC, Attis (Greek god) 1200BC, Krishna (Indian god) 900BC, Dionysus (Greek god) 500BC, and Mithra (Persian god) 1200BC. Does this present any significant challenge for you? Explain.
