Eyewitnesses at the time would be a good start. Historians at the time would be better, since they generally know what they are talking about, and are trying to keep history accurately recorded. What would be even better would be the writings of Jesus himself...but they don't seem to exist at all.
I think Jesus existed because of the evidence of people hailing him as the messiah so soon after his supposed death. The quick growth of the church is another factor pointing towards some kind of event at that time. However I can understand how people can think that he never existed. The primary evidence is non-existent, and the secondary isn't that good at all.
