I believe jesus existed, although this is a really big story and a huge discussion. I have also been to his grave and seen the place where he was crucified, however this of course does not mean that he was the son of god or anything, but i think we can be sure that he existed as a historical person.
I believe in god and jesus myself, however its one of these things you were taught to believe and perhaps works as a "placebo", like "please make me pass the exams" and when you do you say "god helped me". Im not like that but i think you see my point...
