Atheists: How could a man like Jesus have dramatically changed the world?

uming you have at least some intelligence to believe this man existed, what was it about him that caused millions upon millions over the last 2000 years to follow him? After all, if all he was in your eyes was just a moral man, then how can you explain the vast multitudes that have believed in him? Do you really believe millions of people simply became delusional and imagined him to be the son of God, did incredible miracles and rose from the dead? Sure, you could say the same thing about Mohammed but I would rather just focus on this one man. There are countless "moral" people that have existed for the past 2000 years yet only Jesus had the huge impact to change society. So what was it about him that caused this dramatic change?
