"There is no specific physical evidence for the key points of the story."

Try the Shroud of Turin as just one example of the historicity of Christ. Other miracles associated with Christ and his Church still observable today:

Eucharistic Miracle of Lanciano
The Tilma of Guadalupe
Incorrupt bodies of the saints
Fatima
Sudarium of Oviedo

With so many miracles associated with Christ still observable today, why should we be skeptical of the Biblical account of Christ's birth, attested to by Christ's Church?

My kids have brought up this point. The elites work overtime constantly to attack Christianity. Why?

Are they afraid it is true?
