Disbelief is a constant shadow of belief. Avoiding descending into the that death pit is a constant challenge for believers, and if you're an ex believer, you know that. As no one is born believing, every single one of us has experienced full disbelief.
Personally, as a fallen believer, I had little understanding of my former theism. YMMV. As someone who has never experienced belief, and that includes the vast majority of people who believed without understanding/ don't believe due to "lack of evidence", you will have no concept of belief in God, as is demonstrated ably by misunderstanding.
