Magic is a word to define something, and that something is typically a black box which something from nothing typically comes out of, with a world like alchemy at least there is a system. You can argue that's not exactly what magic means or whatever but again that it self would be subjective. We have a toddlers understand of reality, a child from an uncontacted tribe would think it's all magic, modernity. Think of the cargo cults of WW2, they thought the could bring back the soldiers with 'rituals' that they saw them doing, they couldn't. With no basic understanding of something it's magic.
There simply no free lunch in this universe, and we are stuck in it. Perhaps outside of our reality there is but we arnt there.
