(1) If a hypothetical creator can create morality from nothing, he can make it whatever he wants.
Doesn't follow. Also, the very idea of "creating morality from nothing" makes no sense to me at all.
(2) If he can make whatever he wants, it can be arbitrary.
Sure, but you're building on an assumption that doesn't follow.
(3) If it can be arbitrary, it can be deemed moral to forever torture babies for no crime they done in severe torture/pain with no end to it.
No, it can't. People can "claim" such a thing is moral, sure. But when asked to present their argument that underpins that statement, it will very quickly fall apart in a thousand pieces.
(4) It cannot be in any possible world that it's moral to forever torture babies for no crime they done in severe torture/pain with no end to it.
Well, we only have this world to evaluate and we don't know what is "possible".
But I can certainly
imagine a world where it would be moral to do so when it gets presented as the "lesser of two evils", where the alternative to torturing innocent babies is even worse.
In *this* world however, the one we live in, indeed, I can not imagine a context where that would ever be moral. Or not immoral.
(5) Therefore morality can't be arbitrary. (combination (3)(4))
I agree morality isn't arbitrary. But not for the ludicrous reasons you laid out here.
Rather, because of what morality
is. Morality is about human behavior, about how we treat each other. Morality is also undetachably linked to well-being and suffering.
So yes, there absolutely are right and wrong moral answers to moral questions.
But not for any crazy extra-ordinary magical reasons. Instead, simply because of what morality is all about...
(6)Therefore a hypothetical creator can't make it whatever he wants.(combination (5)(2))
So this hypothetical creator is bound by what morality
is, just like any other moral agent.
The age old idea of "
Is X moral because god says it is, or does god say that X is moral, because it simply IS moral for reasons other them him saying so?"
In other words, morality does not come from such a hypothetical god.
(7)Therefore a hypothetical creator can't create morality from nothing.(combination (6)(1))
(8) If a hypothetical creator can't bring in morality so can't evolution since a hypothetical creator can create everything evolution can (structure wise).
(9)Therefore morality exists eternally.(combination (8)(7))
This is false.
Morality is something that is inherent to social species. It's an inevitable consequence of being a social species. You can't have prospering, thriving social cooperative societies UNLESS there are at least some ground rules on how to organize such a society and how to regulate behavior in that society.
So morality is not a thing that requires "creating". Nor is it a thing that exists
independently of social species (like humans).
Morality as such is an aspect / property of the human condition.
If you remove all humans from existence, or all humans except 1, then morality no longer is a thing.
(10)If morality exists eternally, it includes all levels of moral greatness and possible goodness.
This makes no sense to me at all. It's meaningless.
(11) The only being that can see ultimate morality is God
Therefore God exists eternally. (combination 9, 10, 11)
Doesn't follow.
Bare declaration.
