That is the crux of the matter, pun intended.<quoted text>The fact that it was found with other early gospels such as The Acts of Peter and the Twelve later than other texts were found does not give you the age of the texts.
Biblical experts have placed the writing of the Gospel of Thomas between 40 AD and 140 AD, earlier than some of the writings you accept as authentic.
You really are just willfully ignorant.
There were no 'original' documents from which the Bible you use today was translated. There have been no originals found to this very day. Yet books that could possibly be originals, you totally discard because in 325 AD Constantine ordered a conclave of bishops to make decisions for you. That's just hilarious.
That Christinaity refuses to admit the truth about its creation is the prime reason to reject it as truth.
