Atheists are allowed to express their religious views too. Agnostics, too.
If God is the highest most knowing being in the universe, and one knows there is no God, one may then be the most knowing being and is in fact God. I would say, there is a God, don’t worry — he’s got the whole world in his hands … or our atheists do.
As a conservative Calvinist Christian, I understand there are no easy answers, and a qualified absolute statement on God is hardly a basis for living by happenstance.
