Value, maybe. But you would be hard pressed to find a person who would call it more artistic.Here is your assumption. It's entirely incorrect.
I propose that every mother and father gladly value their 3 year old's crayon drawing over the mona lisa. To them, the success and love this represents would far outweigh the high art of a long deceased generation.
Perfection, as far as we are aware, is undefined- and the debate of what perfection is, is more of a head-scratcher than the existance of deities.
Until we come to an adaquate understanding of perfection, it is not a tool which can be used here to much effect, and as different gods all claim to be perfect, well it becomes more of a reason to doubt perfect deities.
Side line: 'God' Hypothesis, I am aware this hypothesis contains infinite regression.
Recently biological scientists were discussing sendings genetic material in space craft off to the distance 1000 exo planets we have discovered outside our solar systems. To reproduce on a mass scale. The plan was turned down as preposturous and vain.
Now imagine, another race long long ago, in a galaxy far far away, was not so strict. Imagine they sent their genetic material to our world.
What evidence do we have for this?
-Speciation genes. Almost all living things have genes for speciation- which deliberately accelerate their evolution, this would be a priority for reproductive aliens, because without fast evolution your new world would be very boring and may not adapt to the strange conditions.
-Lack of life elsewhere. An alien civilisation keen to reproduce would probably not destroy other cultures to do so, this is the fear our own scientists had, so they would send out their seedlings to sparsely populated regions of space- like our own.
-The drake's equation. This estimate indicates that intelligent cultures don't last long by any means, so an alien civilisation would have extinction on the brain (if they had one), making sure that their genes survived- the universal biological purpose- would mean spreading their seeds before it was too late.
