Do you think there are objective values? That we can for instance say that something is good or evil. Or do you think all values are subjective and just created by human will? To give you an example: Most people would say that killing another human being is evil. Still there might be people which think the exact opposite (for instance killing during war is ethically justified and therefore good etc.). Can we say that these people are wrong with their opinion? I think the LOO actually would state that there are no objective values in creation/nature. Values only come into existence because human beings create them, e.g. when I believe killing others is evil.
So the LOO is also in contrary to the teachings of the church which says there is natural law, that is objective values which are hidden in nature. Above I added a video of Graham Hancock who also discusses this question.
