well i believe that objectivity cannot be achieved. but when you say that morals are objective and murder, rape, lying, wearing fur is always wrong no matter how some cultures or some eras have thought about it, then you will need to have absolute certainty because you are talking about absolute and universal values. and if you claim those values are objective no matter what than you gotta prove your claim beyond all reasonable doubt because if you dont it can always be asked How do you know that what you say is the truth and can you prove it to be so.
the problem is that none of the traditional answers hold up if you are really critical.
the culture relavist theory fails but the surface difference theory fails as well because the fact the it happens to be so that all the current cultures and as far as we know also the past cultures only differ on the surface this doesnt mean that a (human/reasonable) culture in which the morals are radically different could not exist
then you have the veneer theory which is at war with the biology/social animal theory etc etc
