Where is that I "buy into it"......I have often said that I can concede the existence of Yeshua.
Therein lies the difference. Jayhawker Soule has commented more than once on the foolishness of the mythicist argument. It isn't a matter of "can concede" but rather to assert that there is any other plausible explanation for the data than a historical Jesus is bunk.
I think there is a "possibility" he existed. For me there hasn't been anything presented that convinces me though.....
And here you are seperated from Jayhawker Soule, not to mention virtually every expert.
Tell me something: what exactly have you read about first century judaism, the nature and genre of ancient texts, ancient history in general, the historical Jesus, and all other related topics? As I mentioned earlier, it is easy to find things "debatable" if you aren't familiar with the data. Jesus' existence is very debatable, until one actually studies the topic.
And I suspect that you aren't "convinced" because you want to believe Jesus didn't exist. Otherwise, why doubt the line in Josephus concerning Jesus' brother, when there is virtually no Josephan expert who does, and all the commentaries on this line say things like "we can know with great certainty that this is genuine."
As for evidence presented, this is a forum. The typical book on the historical Jesus is over 400 pages. Many are in several volumes. You aren't going to get depth on a forum. That being said, there are many simple facts which make Jesus' historicity obvious, even if one accepts a view like Bultmann where sayings and teachings were freely attributed to Jesus and we can know next to nothing about the historical man.
1. First and foremost, one has to understand how sects work, particularly in the ancient world, but even today. They are founded by charismatic leaders, who gather enough followers around them to begin a movement. Cults (like Mithrasa) which are devoted to myth almost never believe their god actually founded the cult, and they certainly don't put him in a time and place within a few decades. All of the myths of the ancient world concern events taking place so long ago that verification is impossible.
2. The gospels only look like myths to people who haven't read enough primary texts of myths and ancient histories. They clearly contain ahistorical data, but so do all histories.
3. Paul, the gospels, and Josephus all agree that Jesus had a brother named James, and Paul knew him.
4. Christianity spread outward from Jerusalem, where Jesus was executed. Had Jesus never existed, plenty of people would know. Even the biggest cities weren't that big, and Jesus supposedly attracted a great deal of followers during his life, certainly enough that had he never existed, stories about crowds and followers would immediately be seen as false.
5. Paul was Jesus' contemporary. He may have known of Jesus while Jesus was still living, and even met him, but he certainly wasn't a follower. However, he converted while all the 12 and Peter and other eyewitnesses still lived (as well as Jesus' brother). And although Paul concentrates on disputes and problems in the early churches, and on the risen Christ, it is clear from his letters that he believed Jesus lived and died during Paul's lifetime (he knew Jesus' brother, he talks about the last supper, Jesus' teaching on divorce, and Jesus' death).
6. Despite the fact that the christians were well known enough to be blamed for Nero's fire a few decades after Jesus' death, and despite our records of those hostile to christians, nobody challenged his existence.
7. We have several independent sources concerning Jesus, more than virtually anyone from ancient history: Paul, Q, Mark, John, Thomas, and possibly M and L. At least three of these sources date while eyewitnesses were still living.
The list goes on.
