Any accounts of how there are moral facts? As in why they exist rather than not? (not if they exist)

I understand the arguments for moral facts and against, however what has always seemed unintuitive to me was how those facts got there.  This I guess is sort of an addendum to Mackie's queerness argument - not only do strange things seem hard to imagine existing, but it is hard to imagine a reason for them to have come into being.  At least divine command theory has the part where god says 'Thou shalt not...' and then poof!  A moral fact!  The same thing works just great for subjectivists, you experienced a moral imperative!  There you go, a moral fact for you came into being.  But how else are there some moral facts rather than none?  I can imagine astrophysical explanations of the universe, but giving a physical account of moral facts would be for most people, a category error.

I realize that many probably wouldn't want to consider moral facts as becoming but rather as being (although the 'why do moral facts exist rather than none' I think gets that across without reference to becoming), but if anyone has thought about it, please help.

If you accept them, its kind of like asking why mathematical facts exist rather than none. It would be bizarre if there was no mathematical facts. Reality in general simply requires it. The implication is that morality is the same. Even if nothing concrete exists, the potential for things to exist and exist in relations that are moral is still there. If you consider it like the math of morality then the facts exist for the same reason as other universals.
