Not to pile it on any further, but Jesus almost surely existed. And you really should have explained what you really meant behind your claim that he didn't exist if you wanted to be fully understood.
This is pretty much understandable.
I'm not being an oh so angsty 16 year old atheist who goes on the Richard Dawkins forums when I say that I hate christianity. I hated it when I didn't even know what atheism was when I was scared about going to hell when my grandfather sat me on his lap and told me about what hell was like and how I'll probably go there because I wasn't baptised.
This is pretty much understandable.
