No, it hasn't. There are over 100,000 copies, manuscripts, and scrolls/etc. dating back to the 2nd Century that have the EXACT same text that is available now.
It's a very well-studied text.
Yes it has been rewritten. SEVERAL TIMES.
But even if one was to play your game...the stories in the bible weren't even put to paper until DECADES after Jesus' death. It's just ridiculous to believe anything in it is reliable.
The talking snake. The flood. Humanity being the result of incest. The order in which god created the earth (which, @
Napoleon had a hilarious infographic highlighting the scientific impossibility of)...I could go on and on.
And when people call believers out on this nonsense, they resort to one of two things, usually: the god of the gaps - to deny evolution, or they hide behind the interpretation blanket.
It's all a bad joke.
Believe in what you want. Just don't legislate and impose this fairy tale over the lives of others.
