The Books Are Not Accurate
Some believed that the four gospels in the Bible were written between sixty-six and one hundred ten A.D. The description in the Bible was written after His death. We might think it was not long ago before it was written, but there might be a chance that the one who wrote this explanation did not witness how Jesus lived on the Earth with themselves. It might be possible that the record was altered by the person who passed the message to the newer generation. There was a chance that the transcription was different from the original life of the Messiah.
Factual Error
However, if the person who saw the life of Jesus while he was living did not write everything by himself, it could mean there were factual errors in the Gospel because one might alter what surely happened in his life. Also, most errors were carried until our current era. Especially this one factor, it was the most inaccurate description in the book.
