The fact is that there is no CONTEMPORARY evidence that jesus ever existed. Given that he went around Galilee preaching to 5,000+, performing miracles, preaching at the local temples and upsetting the userer's tables, that's a bit odd, especially as we had all those Romans writing things down.
The first non-christard reference that occurs was by Josephus in 94/95 AD (60 - 61 after jesus popped his cloggs). The two passages that refer to jesus were little more than a sentence one of which has been shown to be a definite insert by early christards. Looks like they lied even back then. There's question marks over the second also. In addition, Josephus lived less that 30 minutes walk from where jesus lived and yet never mentions it. Josephus' references are secondary pieces of evidence questionable at best. What was Josephus' source? Who knows, he doesn't say.
The next reference doesn't occur until 106 AD in Tacitus. That's 87 years after jesus popped his cloggs. This source is thought to be genuine and not a christard insert. However, at best, this is a tertiary source. What was Tacitus source? Who knows, he doesn't say either. Again, this source amounts to a sentence or two.
So, the 3 sources amount to less than a paragraph between them, one of which even scholars dismiss as being a christard insert and non of which are contemporary with jesus.
This IS the evidence for the existence of jesus - apart from the babble.
