Now there was about this time Jesus, a wise man, if it be lawful to call him a man; for he was a doer of wonderful works, a teacher of such men as receive the truth with pleasure. He drew over to him both many of the Jews and many of the Gentiles. He was [the] Christ. And when Pilate, at the suggestion of the principal men amongst us, had condemned him to the cross, hose that loved him at the first did not forsake him; for he appeared to them alive again the third day; as the divine prophets had foretold these and ten thousand other wonderful things concerning him. And the tribe of Christians, so named from him, are not extinct at this day.
(I took this quote directly from the website given above). Scholars are also in disagreement whether or not Josephus wrote this or whether it was a Christian addition later.
My point is that it will be impossible for a court to find whether Christ existed or not. My personal opinion is that he did exist. It seems hard to believe that all of the writings of the New Testament were created around a lie. Anyway, have fun reading the primary texts.
