Where did the Jesus myth come from?

[Minimalist]

The question to ask is who started saying Jesus is only a myth,and why would they want you to believe that. There is only one man to claim to do the things Jesus did... walk on water, make the blind see...ect. only jesus and ask why is it that people were inspired so much by this man name jesus
so much that they started counting the days for his return A.D and B.C. its only been 2012( how do we know today year) years since he lived thats not that long ago compare to what the government claim to know about things,people,animals,events that they claim happened millions of years ago yet they claim not to know if yes he did exist or not?

Are you really this fucking stupid or are you just another troll? Either is completely possible because most of the xtians who show up here don't know their ass from their elbow but you really seem to be even worse than the run of the mill assholes among them.
