1. If God exists, then God and God alone decides what is (truly) right and wrong. Without God there could be no ultimate standards of morality.
IMO there are no ultimate standards of morality pertaining to all that is considered creation.
Even the OT had different standards for Hebrews and non-Hebrews as in Leviticus 25 concerning slavery.
Also Deuteronomy 23:20
You may charge interest to a foreigner, but to your countrymen you shall not charge interest, so that the LORD your God may bless you in all that you undertake in the land which you are about to enter to possess.
The Bible itself shows that the human application of "right and wrong" changes over time and is relative to the needs of the individual, culture, or group.
I would think that any moral argument for God's existence would need to show that an ultimate standard of morality actually exists for all that God created.
