№ 1:
It is revealed—again, surely without a doubt—that God and the afterlife ARE NOT real. What caused you to believe in God is just programming. Do you continue to practice the Faith, even though nothing really matters?
№ 3:
Same as № 2, but God is the creator of whatever created the simulation. Some Christian doctrines are be inaccurate or outright false, but there is one omnipotent creator God.
Do you continue to practice the Faith, allowing for changes to doctrine or not?
