Is the concept of resurrection unique to Christianity?

Answer 1

No, its also in Egyptian mythology courtesy of osiris and Isis. But the life and times of Jesus Christ are loosely based on the life of Mithras who also resurrected, Oh and there's also some stuff about resurrection in Chan Buddhism.

Answer 2

In Isaiah 7:14, Isaiah prophesied that 'the young woman' would conceive and bear a child, whose name would be Immanuel, a prophecy that came true just a few verses later in chapter 8. However, the early Greek translation of the Old Testament, the Septuagint, mistranslated this to say that a virgin would conceive and bear a child. In the New Testament, Matthew used the Septuagint Greek translation of the Hebrew Bible to 'prove' that the virgin birth of Jesus had been prophesied. This was a misunderstanding arising from a faulty translation from Hebrew into Greek and may have been knowingly taken out of context.
In an example of a prophecy of virgin birth that had not yet occurred, Zoroastrians believed that the Saoshyant, a saviour who will lead humanity in the last battle against evil, would be born of a virgin.

The concept of virgin birth was also quite common among ancient Mediterranean and Middle Eastern religions, particularly the "Mystery Religions". In fact, by the first century CE, it was almost expected that godmen would be born from virgins.

Answer 3

Not at all. Miraculous or Virgin births occur in historical literature and religious texts. If Christians would look to the old Babylonian paganism, they would soon discover how many of the attributes given to the Virgin Mary by the Roman Church are quite similar - 'all the attributes given to her are derived simply from the Babylonian Madonna, and not from the Virgin Mother of Christ.' (The Two Babylons by Alexander Hislop, chapter VII, section IV, The Image of the Beast).
