You're committing the same fallacy with purpose as you do with morality.![]()
It's only a 'fallacy' because it doesn't happen to be the same view you hold!
You believe that there's some supra-human plane upon which these grand standards are set, and then we are judged against them. You cannot conceive of something like morality or purpose having a humanistic, or natural grounding, and it's very sad to behold.
You are correct that I don't see any grounds for objective morality outside of this 'plane' you mention.
I accept that we as humans are capable of displaying socially acceptable behaviour.
The huge problem with your view is that you can't seem to admit that in all possible societies raping a child is totally wrong.
The whole beauty of there being no such abstract plane, and no such standard is that there is no grand purpose. But what does that actually mean on a human level? It means that everybody's life is what they make of it. We can assign purpose to our own lives, and make them to be about whatever we want. Any notion of grand purpose, the idea that we were 'created' with a purpose, is of course illusory, but that's a beautiful thing. It's beautiful because it allows the possibility of up to seven billion different purposes to life.
You seem so certain that no such plane exists. How can you be so sure? Are you ruling out the possibility of it actually existing?
