How can you look at the past 2000 years of human history and say that Jesus didn't live? That's ignorant, friend.
ignorant? really? to ask for proof of the existence of a person who allegedly did so much but managed to leave so little evidence?
We have nothing he made, nothing he wrote. We do not know where he was born or where he died. We do not have his body and we don't have those of his relatives. We have no records of his existence, no third-party records (save that collected together, both canon and non, in what we now call "the bible"). We don't know when he was born or when he lived. If he caused a revolution in his own time there is no record of that. We don't even have his death-warrant by the person or persons who are said to have condemned him.
Is it so much to ask for some proof?
I'm assuming you have something else than the bible?
We don't need real people to change the way society thinks - the church of the jedi's proves that. Co$ and it's madness proves that.
We don't need real things to have happened to create cults and religions - mormons prove that (sorry, Mormons, but a magic hat and rock? seriously?).
Muhammed lived, we know that. We know where he lived, where he died, what he looked like (despite muslim's violent tendencies about pictures nowadays, there are many pictures made in antiquity of the man). His claim to being a prophet is something else that is essentially unprovable except through faith, and in that he's very similar to any historical Jesus.
