Apologetics open challenge

[TheRocketSurgeon]

I nearly forgot about this thread.

Here's another argument:

God cannot decide what objective morality is, or else it would be arbitrary. 
Objective morality thus cannot be created by God.
If God cannot create objective morality and decide what is, then neither can evolution, as God can create evolution.
Objective morality exists.
Thus objective morality is eternal.
Objective morality takes a perception to see.
Thus an eternal being who perceives objective morality always existed.

I found your problem.

I'm afraid there is no evidence whatsoever that "objective morality" exists. There are things we pretty much all agree on, as social animals (aka humans), but by no means are they defined in the same way, and even something obvious like "don't kill" and "don't rape" are defined in extraordinarily different ways, across cultures. There is no one thing you can point to which is "objectively" moral, and the arguments made for "objective" morals in the Old Testament, from which all three "Abrahamic" ideologies draw their concept of morality, are demonstrably horrifying by modern standards, and clearly the product of patriarchal, Bronze Age tribal sheepherder thinking: slavery and indentured servitude for debts (for other races and for one's own people, respectively), rape of women treated as a property crime against the men who "own" them, murder of disobedient children, murder of those who practice freedom of religious conscience, genocide, and dozens of other absolutely and utterly immoral ideas by modern standards. This clearly and unequivocally shows that the claims of "moral objectivists" cannot hold up under scrutiny.

Since your entire argument hinges on that single proposition, "Objective morality exists, Thus...", it unravels upon scrutiny.
