I would suggest that you read a book called 'The case for Christ' written by Lee Strobel. It's written by a journalist who investigates the evidence for Jesus.

The four gospels (matthew, mark, luke and john) are based on either direct or indirect eye witness testimony.

The fact that the year being 2005 AD, means 2005 years after the death of this 'Jesus'.

Theres a lot of supporting documents outside of the bible too, written by Josephus, a trusted historian, and Tacitus.

There is better documentation for Jesus than for the founder of any other ancient religion.
