From atheism to tentative agnosticism

[MikeTheInfidel]

Well, because morality is normative: it instructs and favours. When I sense that an act is morally wrong it appears to me that the act is in some way 'not to be done' - it is as if the universe itself wishes me not to do it. ... Now, perhaps we are all just suffering some kind of hallucination when we sense that some acts are right and others wrong. Perhaps there is no rightness or wrongness out there in reality. But most of us have the impression that rightness and wrongness exist. And it is hard - hard for me, anyway - to make sense of how such features could really exist unless a god exists. This is not to say that a god exists, just that morality - if it is to be real - requires a god.
Because I think morality is real, this raises a doubt about atheism.

Human morality is an instinct which we have evolved. We see similar moral behavior in other social animals, such as wolves and chimpanzees. There's nothing supernatural going on here. You have a deep, gut feeling of morality and immorality for the same reason that you feel an instinctive need to eat or breathe. None of these are indicative of some greater, powerful, creative force. Our moral instincts have been part of our species' survival. And beyond our basic moral instincts, which acts we consider moral and immoral are the result of social conditioning.
