I came across this argument that "absolute moral values can exist only when God exists" (http://www.youtube.com/watch?v=yqaHXKLRKzg). I have been trying to figure out some logical proof for moral absolutes from an atheistic perspective.
There are plenty of ethical systems that are
non-theistic, in that they do not depend on the existence of any god(s) for their validity -- Kant's categorical imperative, Bentham's and Mill's utilitarianism, Rawls's original position, Reid's intuitionism, Smith's sentimentalism, etc. etc. etc. These aren't atheistic, and a belief in god can be easily reconciled with them, but they can also be reconciled with a
disbelief in god. I'm not sure if there are any systems of morality that rely on the
nonexistence of god(s) for their validity, but then I can't imagine why anyone would bother.

I don't know if any system of morality has been subject to a widely accepted proof.
