The Earth orbits the Sun. Once upon a time, we didn't believe this: We thought that the Sun orbited the Earth.

The Sun does orbit the Earth, but that fact is not particularly relevant to why it appears to rise every day.

If you want to bring up the debate regarding heliocentric versus geocentric views of the universe, remember the debate was really about what was the center of the universe; that is, whether everything else went around the Sun or the Earth. (the answer, of course, is 'both' for any reasonable definition of 'around'). The question was settled by which interpretation made the math easier / more beautiful.

Also remember that Galileo exaggerated the debate significantly.

ETA: And, of course, we now don't consider the Earth or the Sun the center of the universe.
