Let’s put it this way I’m pretty sure if you read this here blog you know I don’t believe in any sky fairies aka gods. None of them.
But today I’m going to pick apart the Bible that everyone loves to wave around to quote scripture, etc.
1) The number of different versions of the Bible gives me pause. There is the KJV, NIV, and many others out there where the language is changed just so.
2) I know the Biblical texts were written anywhere from 30 to 80 years following the alleged life of Jesus. Can you tell me what you did 30 years in the past?
3) During the time of the writing of the New Testament literacy was not common as it is today. So the story must have been passed via oral tradition. If you ever played the childrens game of Telephone you know a message morphs big time if N>2.
So just those three – leaving out translation error, copy error or even scribes changing text. Christianity is only based on so much woo. Even the term Christ is Greek for Messiah.
Spewing Truth in the face of Lies 
I certainly agree with that. None of the people who wrote the New Testament were alive when Jesus supposedly was. As you said, the earliest of the gospels was written at least 30 years after he died. Mark was written somewhere between 60 and 70 AD, the other three written even later. So all of it is based on hearsay, anecdotes, etc.
