The Romans thought that the Christians were atheists because they didn’t believe Caesar was a god.....almost like today where “god” is oneself....
Most of the Jews thought that Christianity was a vile group of people who followed a false dead prophet.
Coming back from the dead(with no human help) has a way of dispelling those notions... You don’t get a cult with someone who has come back from the dead in a human physical body. You get a new paradigm of the existence of the world and ones own life.
People who don’t believe life can come from dead things need to recheck the modern theories of abiogenesis.
Ben Shapiro, (whose current political views I mostly ascribe to, but who is an irritating little snot) when asked if Jews consider Jesus a prophet, stated, “No, he was a criminal!”.
