No friend, there is not only one bible. Because it has no original language. It had been got away from its original meanins by while the religious leaders was translating into their languages without keeping its original language near them or the religious leaders had changed a few, some or lots of parts of the bible to gain benefits from people.
Isn't this example proving this idea?:
Did priests sell lands which is in heaven for money?
Do people go to church to get away! from their sins by paying to priests? (I hear you say "no priest take money to delete people's sins!".)
I ask you: "Do you believe in bible?"
You say: "Yes, I do."
I ask you: "Which bible?"
You say: "All bibles are the same." (Let's accept for now that is true)
I ask you: Bible in Iraq, Bible in Rome, Bible in New York, Bible Matta, Bible Markos, Bible Luka, Bible Yuhanna, and Bible Barnabas. Do you believe them.
Probably you will say: "Yes, because they are all the same."
Now I am offering you to read the Barnabas bible and see difference you have read before.

Now will you continue to say "all bible are the same!" or "there is only one bible!"?
Maybe you will deny some bibles huh?
