I'm not convinced. Most magic systems in fiction have rules, meaning they can be scientifically proven and studied. Magic is simply when something falls outside your understanding of how the world works. It's all about your perspective.

There's a part in the Lord of the Rings where Galadriel shows Sam and Frodo a scrying pool. To Galadriel it's normal, simply the way the world is. To the hobbits it's magic.

‘And you?’ she said, turning to Sam. ‘For this is what your folk would call magic, I believe; though I do not understand clearly what they mean; and they seem to use the same word of the deceits of the Enemy. But this, if you will, is the magic of Galadriel. Did you not say that you wished to see Elf-magic?’
