What Is It That Calls Out for an Explanation?

i don't feel like i understand god's existence any better from being told that his existence is necessary, especially when his existence only necessary given his existence. That's why it fails an explanation to mek. So what i'm thinking here, minimally, is that things that are not automatically actual sort of call for an explanation in a special way because they could have not been actual, but are actual. And the very fact that it's actual rather than it could have been not actual, your mind just might feel like a there just needs to be an explanation.
