If God and Jesus were proven to never have existed, many Christians would still continue to be Christian.
And if God were to step out of the clouds and reveal himself to all of humanity, many atheists would still refuse to worship and follow him.
"Logic, reason, and evidence" has nothing to do with it.
It's all about faith.
@JCAlexandreWrites Last I checked, no god has ever been proven to have existed in the first place. If one arrives with irrefutable evidence of proof, I will believe.
