The Shroud of Turin - Authentic Again!!!

[Sigurd]

We have no evidence that the gospels were written down at all by the people they are named after. What we have are people writing what they claim was written by people writing about the people writing them.

I guess you should say scientific evidence here, as in the paper it was written on have been dated so and so.
There is other scholastic evidence to be found, in the texts itself. Events that transpired, people mentioned, the way things are written, handwriting, texts being copies etc...
I could mention the Didache or the writings of Clement who make frequent quotes from the Testaments. It is generally believed amongst scholars that these texts are 1st century texts. But again there is no scientific evidence for this. No copies exists that you can make a Carbon14 test of and prove that this organic paper was from a plant that was cut down in 50AD. You only have a full copy written in about 1050 AD and you have scholars from the 3rd century making references to it... oh and an orthodox excerpt (5th century) quoting from it and dates it in its header to 90AD.

Then you have the Christian scholars that want to date it prior to this. The closer to the events the better it is, right?
They analyse the texts and find a reference to the temple of Jerusalem, that sacraments are being administered at the temple in Jerusalem. They then claim that this text must be prior to the destruction of the temple in 70AD and hence a copy from the original which must be from before 70AD.
But still, it is 40 years after the events of the crucifixion. 40 years of trouble and persecution from the other Jewish sects.
And of course if they establish these non-canonical texts as before the destruction of the temple in Jerusalem, they have then made evidence for new testament books being even earlier texts (the quotes from these testaments).
