So atheists, that guy Jesus never existed right?

Early Christians just went through persecution, vilification, and death for their belief in a guy that never existed for fun? (damn masochists). And the massive spread of Christianity in a matter of 200 years was just luck. The false image of a man nailed to a cross and killed (which even the Jews, who "Jesus" claimed to be the savior of, dismissed as a liar) luckily spread through a massive empire and led to the creation of the largest religion in the world today. That makes perfect sense right? (Try to to answer with straw man arguments.)
