Why do some people make the absolutely absurd and desperate assertion that “Jesus never existed” ... Say what!?

Because there isnt any solid evidence that he actually existed. I mean the bible is like 1000 years old and was written about 50 years after the events in the book happened, thats like playing a game of chinese whispers for 50 years, so you cant really blame people for being skeptical. Just because the bible is deatailed doesnt make it true. Just like the harry potter books being detailed dont make them true.
