The rules for magic and the rules of existence in most fictional universes are significantly more defined (and, arguably, more solid) than the rules for science and existence in this world.
Even the brush off of "Its magic. I don't have to explain it," at least indicates that SOMEONE understands the effect
and its relative existence.
If you find 5 people who say that they fully understand a single branch of science then I'd bet all of my money in my pocket that you found them in a padded recovery room sans shoe laces.
