And it explains how you are wrong when you claim God is not all powerful if he did not create evil.
God can't go against his nature. He can't oppose himself. It is silly to say that something which makes God stronger is a sign of weakness.
Evil is not extant. Evil is the absence of good. Everything that was created is good. 14 billion years ago God created existence. How can that be bad?
How do you know that god can't go against his nature? How do you know that god didn't created bad things on purpose?
Men lusting after and raping little children is evil, and it exists their whole life and is a part of their personality, so extant. Now what I want to know is WHY did god put such an evil thing in this world?
