The “a good God cannot exist if there is evil in the world” argument:
1:if a good God exists he wouldn’t allow evil to exist
2:evil exists
3:therefore a good God cannot exist
The problems with this argument:
1:what you are basically saying is that a good God wouldn’t allow freedom
2:you for sure don’t know if a good God wouldn’t allow evil in the world for some good reasons.
3:there's the idea that without evil there wouldn't be such thing as love
4:there's the idea that God allows evil in the world so we will get prepared to become who we need to become.
5:if there's such thing as evil there's a God and i explained in the moral argument why this is.
