This seems like a real flimsy axiom to put the basis on.

Well I couldn't do anything without my parents having taken some action for me to exist, and they couldn't have done that without their parents, so is all original work actually belonging to the first semblance of life?

Or how about, my wife and I decided to buy a deck of cards for date night ideas, and one of the cards said that we should paint portraits of each other. Are the paintings original work of ours, or does that belong to the card creators who inspired us to do it?

If instructions are all that is required consider art not original work; then I really don't think we should give Michelangelo any credit for the Sistine Chapel. He was told to paint it by the Pope.
