There are about 5800 manuscripts and transcripts that back up the Bible. Their similarities are nearly verbatim. So records over 2000 years that say nearly the same thing from all parts of the world has some merit. The New Testament was completed in about 96 AD and all but Revelation was completed by 70 AD. The writings were by the actual participants or eye witnesses. There is very few writings that call the Bible a fraud and they are far more unreliable than the Bible.
The death burial and resurrection of Jesus took place in Jerusalem when there were millions of people around but no creditable evidence that what is recorded did not happen the way it is recorded.
There is a book called The Case for Christ(IIRC). It examines the life of Christ and concludes that the Bible is true. I was started by an atheist to disprove the Bible but the further he examined and dug into the Bible the more real it became. You should read it.
I mentioned the 5800 transcripts for the Bible in the time frame of 100 years. The entire story of Alexander the Great was written 600 years after his conquests and there are 2 copies of that writing, yet mankind believes that recorded history.
There have been more Transcripts and manuscripts of the Bible discovered after the King James Version was translated into English than before its translation but all are true to one another.
