Just like religion, morality required a human to invent it.
That is interesting point. Did morality exist before Adam and Eve existed? Would the lower animals have some moral code established in them? Fro the second question, I don't think so. God gave the breath of life into humans only, and they/us alone carry the responsibility of morals.
For first question, I do believe morality existed before humans. We became the vessel to act on God's moral standards that pre-existed us. Evil existed before we sinned as shown by the Tree of the Knowledge of Good and Evil being present in the Eden story
