Who's to knows what is true.

Who's to know who's right nowadays? You got one book, retold, reprinted, and preached over a million upon million upon million times over the last several centuries. Is it possible that maybe just maybe the story could have been changed over the centuries, the words of the book tweaked here and there to better suit people's needs and opinions?
 I see... it's like a lie told and someone tells someone else and they tell another person and they tell someone else and every time it's retold the lie is changed just a tiny bit so it still sounds good but still a lie. It's just too hard for me to believe in a book that has been reprinted a million trillion times and something not to be changed or left out or pages put in the wrong order. Maybe that's why the bible is so hard for so many to understand because it has been rewritten, reprinted, and retold so many times that who is to know who is right?
