It’s so interesting, because one of the early theories about Earth and its situation in the Universe was the geocentric model…which basically told that we lived in a sphere (around Earth, making it the unmoving center of the Universe) that was contained in another rotating sphere on which stars were “painted” (of course this schema is a sort of “basic idea”, it was discussed and adapted by many scholars on the subject at the time). 

So in fact, this young girl just drew a conclusion on what she could empirically observe and her interpretation would not have been seen this derisive if we did not have the knowledge we have today! Of course we could be living “inside” the Earth-sphere, because the concept of Earth “limits” is an intellectual one, not something instinctively perceived!
