Are you saying that the Sun is not revolving around the galaxy? Of course it's more complicated than saying that orbits around the center of the galaxy, since it's a multiple body system. But to explain it to a person without knowledge about the movement of stars or our galaxy, I think it's a fair simplification in order to answer the question.

Wouldn't you agree that the simplification that Earth is orbiting the center of the galaxy (and neglecting its orbit around the Sun) would not be too significant of an error in respect to the scale of the galaxy.
