Is it possible to rationally prove the existence of absolute goodness

From what I understand, Goodness is an attribute of being as desirable or lovable. In our ordinary experience, what is real is not always so desirable. Not to mention, we also have a tendency to develop ideas of goodness that are not always recognized as desirable. Usually in the form of rules. Natural Law on the other hand, which as far as I know is the primordial understanding of good and evil, due to this natural desire for the ultimate good, and the inherited natural ability to recognize the value of existence.
