You didn’t say Sept 11th 3BC was the birthdate of Jesus, you said it was the beginning of the Age of Pisces. You got your date for the beginning of the Age of Pisces from a commentary on Revelation.
It’s no wonder you didn’t want to tell us how you knew when the Age of Pisces began.
Jesus being born on the first day of the Age of Pisces would be a huge coincidence, and grounds for either awe or suspicion.
Choosing the first day of the Age of Pisces to match when Jesus was born and neglecting to mention it when asked is grounds only for derision.
