So this is where you have all been hiding.

The date of the birth of Jesus has nothing to with the Bible. The date came from Dionysius Exiguus working backwards from 533 AD.
“We have seen his star in the East” (Matthew 2, KJV) has been mistranslated from the original Greek. “We have seen his star appear in the first rays of dawn” would be correct. According to Jewish prophecies, the Messiah would appear when there was a conjunction of Saturn and Jupiter in the constellation of Pisces. This unusual astrological event occurred three times in the year 7 BC and is consistent with the correct translation of Matthew. Also Herod the Great died in 4 BC so 7 BC seems the favorite.
Working backwards from 533 AD being 7 years out wasn't to far off.

Is the Bible true? If it is not true Christianity self destructs.
Do Christians seek God or seek to justify Christianity?
The Bible was put together by Christians for Christians and no system that feeds on itself to support itself is valid. If Christianity is to be valid it must be able to be supported by outside sources.
Is the Bible True? Does it matter? It is only a self fulfilling prophecy at the best.
The existence (or not) of God is something that can only be known to each of us one to one basis. No self fulfilling system can do that for us.

Glad to see you are all still well and active.
