Yeshua the annointed one
There's a detailed discussion on the existence of Jesus over at Stephen Law's blog, which visitors here (assuming there still are any) might want to take a look at.
Personally, I've never found the arguments for the divinity of Jesus convincing. All history is a matter of probability, and the probability of Jesus being able to perform miracles because he's an aspect of a divine being given flesh is always going to be much lower than the probability of more mundane explanations*.
(*Assuming you've had no prior contact with said divine being, which would - if itself valid - alter the probability considerably.)
