Your "deep question" fails to address gspencley's point: If everything we do is a rearrangement of basic known parts, where and when did we get the basic known parts? From cavemen? From apes? From protozoa?
Someone, at some time came up with the basic known parts.
So, was that real creativity, or not? If not, why not? If the parts are really "basic", they didn't come from other, pre-existing parts.
And if it was real creativity, why is it impossible for us to do the same?
