Exactly, and good becomes meaningless if it has no fixed, objective address.
And that is evidence that god exists how? This again seems to be an argument from consequence, this doesn't show anything other than the fact that good may be meaningless (and that our opinion of what is good is meaningless until we can demonstrate that not only objective morality exists, but that we can and do know what it is). You're pointing out something you don't like and stating that because your world view allows you to view the world otherwise your worldview is valid, this isn't a case for your world view unless you can show that morality is objective.
We give a fixed term to the thing you and I call a dog. You understand when I use that term that it does not mean a cat or tree. It refers to that thing and nothing else. When it comes to goodness on any given specific subject the term is interchanged with other meanings, depending on where you live. It can mean the exact opposite. Some countries believe abortion as a woman's choice is wrong/ evil and others believe it is right/good.
This is because dog has a (reasonably) clear and defined meaning, it means a canid, especially the canis familiaris (it can also mean a worthless or contemptible person).
Notice this is a clear definition, the traits necessary to fit it are fairly small, a cat and a tree aren't canids, so they're not dogs.
Now look back at the link I presented for good, it lacks that same traits, if we were to write a definition for good that included the traits and criteria that made a thing good (there are several definitions for good that actually do this, but they're for very specific context), then we'd have a world that clearly meant one thing, it wouldn't however be anymore objectively 'moral' than it is now. The first definition presented for good is actually: of a favorable character or tendency.
That's subjective, that's dependent on circumstance. How about these:
b(1): SUITABLE,
FITgood to eat
(2): free from injury or diseaseone

(3): not

good(4): commercially sounda

ADVANTAGEOUSmade a very
good deal
c(1): AGREEABLE,
PLEASANThad a
good time
(2): SALUTARY,
WHOLESOMEgood for a cold
(3): AMUSING,
CLEVER
3, 6, c1 and 3 are certainly subjective. We have to scroll the page down quite a way before we come to anything that addresses morality directly and then it states:
'something conforming to the moral order of the universe'
That's fine, show that this moral order exists and how we can demonstrate what it is and we may finally have a clear definition of good, but until then, we've nothing to give traits to good within a moral context. You can claim this is why your worldview is better, but what you actually mean is it's why you prefer it. You see I'm not debating what worldview is best, I'm debating which worldview is most accurate to what we can show to be true.
So who is actually right? Which is the true position, since logically they are not both good? You CAN'T answer that because you have no objective best.
It's entirely dependent on what you conclude the moral order of the universe is. I would personally say we've not got evidence that either is good. So I would answer neither.
