Because magic has a very specific meaning in D&D, and it comes in the form of spells cast by clerics, druids, wizards, bards, sorcerers etc. Anything else is not magic even if it looks like it--for example, if a creature has the ability to cast something like a spell but hasn't got a spell-casting class, it will be described as having a "spell-like ability" rather than having a spell. That's my understanding of it, at any rate.
