Do you bake,
Bwark? Would you agree it cam be a creative thing to do?
Do you "create" your own recipes every time? Or do you recognise that certain combinations of ingredients work best in certain ratios?
Are you then copying someone else's creativity?
You mention origin and creationism... confusing origin with creation.
For example.
99.9% of DNA is identical from one human cell to the next. It's the 0.1% that's different.
That's all it takes to be original.
Nobody. Absolutely nobody is 100% original in anything they do...because they are influenced and educated and soak up images and experiences all the time.
We learn by imitation.
Humans learned from each other. Copied each other. Its how we developed as humans.
Go back far enough and you'll see that the origin of our species was a single cell life form ....that split into two cells and then divided again amd again replecating information all the time. Little influencers like bacteria or a virus here and there and what do you know suddenly over millions of years we developed into multitudes of humans. Copying is part of our DNA. There is nothing original about knowledge either. Everything we know is built on the knowledge someone else realised existed.
As for Cadburys? They were not original. They copied a chocolate drink created in South America.
Nothing is truly original. Nobody is truly creative...as in bringing forth something entirely new and unaffected by anything that ever existed.
Every artist is influenced by external factors and other people's work.
