I think Jesus was Jewish because he lived in Judea. People just didn't move around as much back then.
Anyway, wouldn't it be more appropriate to prove Jesus was a scientist?
1. He made a whole lot of food from the bread and loaves, so I guess that makes him a chemical engineer of sorts.
2. He healed a lot of people, which he couldn't have done without doing biomedical research or maybe he just used the power of the Lord. I'm not really up on my Bible studies.
3. Walking on water is an obvious physics trick. Like walking on coals, only with much bigger feet.
4. Overall, I think he was a high school science teacher. He knows a lot of different disciplines of science and he gives a lot of lectures. He also taught shop because his school was ridiculously underfunded.
