The original text are more or less intact sorry, every time they find scraps of older writings such as the dead sea scrolls or older fragments of the gospels they all tie up with the newer ones so please do not propagate the lie that we dont know what they said originally. What we have is likely to be very close to what was written. Scarps of the gospels exist from the 1st century for example and all tie up.
I dont know where you are getting your information from but it is not correct. I am not sure we can carry on a conversation where you are posting things which are known to be untrue such as your claim about what was in the original text.
Different schools of thought exist in academic circles and some are more suspicious of the accuracy or worthiness of biblical texts than others of course but what I am saying is quite normal for some of the groups of respected academics. Certainly not even the skeptics among academic would claim that the Bible isnt at least an approximation of what was originally written.
