I think we need to draw a distinction between evidence & apologetics.
If I say, for example, there's no mention of Jesus anywhere until 70AD, you are NOT providing contrary evidence by saying, "Oh, but that's to be expected, there was no Daily Fail back then, and it was all oral tradition" - you are merely providing an explanation (apologetics) for why you think that might be. You are not contradicting me, or proving me wrong, you are acknowledging that I'm right - just putting your spin on it.
Evidence demonstrating that I'm wrong would be "Actually, he's mentioned by x person in y record in 49AD". Do you understand the distinction? Every single time you try to explain away one of the facts I present rather than contradict it directly and show that I'm wrong, you are merely confirming that I'm right.
I already know that you feel you have an explanation for why there's a lack of information about Jesus. I expect every Christian agrees, more or less, with your explanation. But I don't accept your explanation because you are not backing it up with verifiable data - evidence. And that is what this debate is SUPPOSED to be about - whether there's actually any EVIDENCE that Jesus existed - not whether there's a convincing explanation of why there's no evidence.
Right - for clarity, let's look directly at what we know regarding Jesus. This is what the "evidence" amounts to:
Christians generally claim two sources of evidence that Jesus existed - the Bible, in particular the NT, and a few non-Christian, extra-Biblical sources.
I'll come back to the Bible - but let's look outside of it for now.
We have a lot of Greek and Roman sources from the period - because of this we are talking about one of the best understood eras in the ancient world. It's is absolute rubbish to try and suggest no one was writing anything down because they really, really were. We have the works of religious scholars, historians, philosophers, poets & natural scientists. We have thousands of private letters, inscriptions on buildings & tombs etc.
From all of these people we learn about the different religious cults that there were (and there were many), all of the people who were claiming to be able to do miracles, messiah claimants riding into Jerusalem on asses to fulfil the prophecy in Micah, uprisings being stamped out by the Romans. We are very fortunate to have so many rich sources of detail.
So, if we look directly at the period Jesus lived in - up to the end of the 1st century, what mention can we find of him? The answer is truly staggering. We can find nothing. Absolutely nothing. He is never discussed, challenged, criticised or laughed at. There are no records of his birth, accounts of his trial & death, disputes about his teachings. No passed on rumours about miracles, believed or not - nothing. No mention of any kind from anyone.
Now - is it enough to say, "But they didn't keep records back then, No one wrote anything down"? No. As I have said, the sheer volume of literature produced at that time and in that place is enormous - they WERE writing things down. Lots of things.
Does this all prove that Jesus didn't exist? Nope. It doesn't prove anything - except my assertion that there's no evidence that Jesus existed. If you are opposing me on that, name the extra-Biblical source that names Jesus, or even refers to him in passing, in the first century after his birth? Explanations such as "They kept no records back then, y'know - and no one had heard of him" etc are not relevant to this discussion. Remember please, that I am not trying to prove Jesus didn't exist merely that there's no evidence demonstrating that he did.
WHATEVER the explanation is, the fact remains that there is no source that even hints at, let alone demonstrates, the existence of this man Jesus of Nazareth (no trace can be found of Nazareth either, by the way).
So, we have to wait until about 112AD before we start hearing vague mentions (and they are very vague indeed). There's an immediate problem - the authors of the sources were not actually alive at the time Jesus was and they don't tell us where they are getting their information from - so it's hearsay. This is not evidence and should therefore not even feature in a discussion about the historicity of Jesus - but because Christian's literally have nothing else, they are forced to keep bringing them up.
The second problem (if hearsay isn't enough of one) is that they don't tell us a blessed thing about Jesus anyway. The most they do is confirm what we already know - that there was a religion called Christianity in the second half of the first century. Big deal.
Oh - and if you're going to try and suggest that this is enough to prove Jesus existed, then I'm assuming you believe Mithras did too? People worshipping him were around in far greater numbers than the Christians. As were thousands upon thousands of believers in Pagan gods - does their very existence prove that the god they worshipped was true & real? Of course not. And it doesn't prove that for Jesus.
So, in 112AD Pliny the Younger, who is the governor of a Roman province wrote a letter to the emperor Trajan asking how to handle a group of Christians who were meeting illegally. He explains that these people "worship Christ as a God". That's it. Pliny says nothing about Jesus, never even names him. This is evidence that Christians existed. That's all. NOT evidence that Jesus ever did.
Tacitus is next (in 115AD), and I've dealt with him further up. Again, not a contemporary of Jesus and not passing on anything he's witnessed personally - so not providing evidence of anything. In a tale about Nero in a history book he's writing, he explains that Christians get their name from "Christus...who was executed by Pilate". He calls their beliefs "superstitions".
These two above are the best, believe it or not. The rest are frankly embarrassing:
In 110AD, a Roman historian called Seutonius is writing a biography of the emperor Claudius. In it he says that Claudius drove the Jews out of Rome because they, at the suggestion of Chrestus, were constantly rioting. Christians have always tried to say that actually, he meant, "Christos". Even if they're right, Jesus was in Rome telling Jews to riot? Really? Gentle Jesus, meek and mild? Chrestus was actually a very common Christian name. Seutonius was not talking about Jesus, clearly.
The Talmud: Discussed briefly above, I know, but for those who aren't familiar The Talmud is a collection of Jewish religious and civil laws which includes a commentary on The Torah. There's a briefly mentioned character in there called Yeshua which some Christians have taken to mean Jesus. This is divisive amongst scholars - firstly whether they mean someone else altogether (and there are a couple of likely candidates) and secondly whether the passages are original. In any event, the Talmud did not come into existence until the 3rd century, and it took about 300 odd years to write!
It's truly amazing that anyone thinks this is evidence that Jesus existed - 3 to 600 years earlier!!!
The last one is Josephus - the most important & the one that's quoted the most. It's not evidence for one really good reason - it's an outright forgery. We even have a really good suspect for who the forger is.
Now, I know with 100% certainty that you'll all pile on me and say, "But not all scholars believe that - most think it was only partly forged" (like that makes it better!). No, there's little doubt that it's a complete fabrication. There are some wonderful quotes from Christian scholars writing it off completely, my favourite is Bishop Warburton - "It's a rank forgery and a very stupid one too". He's right.
I will provide an abundance of evidence for this, I promise. Not a single Christian will leave this thread and use Josephus as evidence ever again - the case is that watertight. (Not saying it'll shake faith or anything, to be clear).
So - that's it, outside of the Bible, that's the only "evidence" that's presented for a historical Jesus. Not only is it lame and vague, it's evidence that proves precisely nothing.
Which leaves us with the Bible - specifically the NT. And what's the Bible - books & letters written for Christians by Christians. It's "in house" literature produced to shore up faith or covert others. Hardly what you'd call unbiased then? But the bias doesn't matter. The gospels demonstrate in a myriad of different ways that they are not historically reliable. But I shall get to that.
But before I do, let's thrash this lot out.
