You're not getting. And it's sad, because it's so simple. It requires no belief, no knowledge, it's pure logic.
I'm doing my best here, but apparently that's not enough.
Look, if you as a human can't tell the difference between good and bad, then you can't possibly know if god is good or bad. He can tell you that he is good, but that statement is meaningless, since you have no idea what "good" means, and all you can do is take his word for it.
So the statement "god is good" can never be a statement of knowledge. That's logically impossible.
Guys, a little help to make this even more obvious?
