Most Academic scholars agree he existed, due to the evidence that he did indeed exist. However I've never really found Jesus being a White man to be very believable, he was born in the Middle-East 2,000 years ago...so my question is, was Jesus instead of a light brown colour?
When I hear the term "white" I think European or Caucasian. If that is what you mean then the biblical Jesus was not "white". Theologically it is important that He is a descendant of David. All the biblical genealogy passages make it clear that He was a Jew and therefore would be ethnically Semitic. As with all ethnic groups there are variations in melanin content within the skin and it should be expected that Jesus would have fallen within the normal range of melanin content for a Semitic person in Palestine in the first century.
