These “flat-Earthers” try to argue that a flat Earth can explain all of our observations and, at the same time, they claim that photos and video of the Earth taken from space showing a rotating, spherical Earth are all fakes. That shows a major failure in our educational system.

You might have noticed that there are some people who question whether the Earth is really round, or who actually believe (or claim to believe) that it’s flat. For the youngest students, we could ask, “Why is the Earth shaped like a ball?”

A:Yes, I know, the question should really have been, “Why is the Earth approximately spherical?” The word round is a bit ambiguous, as it could refer to a two-dimensional circle or a three-dimensional sphere.
