Why do you not believe in God?

[Mystic]

Nice try. Don't move the goalposts. We're talking about your one-and-only-true-god-concept here.

But your reasoning was that we wouldn't be discussing it if we have knowledge of it. The same can be said about free-will and morality. So perhaps you can explain why the case of God is different. Why discussing regarding God would mean we have no knowledge of God while the same is not true of free-will and morality.

No. Its not common knowledge.

Whether it's common knowledge or not, is up to people to decide. But one thing for certain. It's a common belief. Most of the world believes in God. This doesn't mean God exists or people have knowledge, but it is a common belief.

Small percentage of people don't believe in free-will. There is no arguments to prove we have free-will that don't rely on some intuition.
Small percentage of people don't believe in objective morality. There is no arguments to prove objective morality that don't rely on some intuition.
