I love looking at the moon. I love watching it slowly change from a full moon to a new moon. I love half and crescent moons also. But they are all the same moon in different light.
By observing the moon and watching it change I can confirm that it is indeed a sphere. By looking at the shadows I can point to the direction of the sun, and infer its location relative to us.
But why should the moon be spherical? The more we look out there the more we realise that the other planets are spherical as well. So maybe the planet we live on is as well.
That thought probably prompted man to sail away from the coasts and literally venture out into open waters. The evidence increasingly pointed to the world as being round, or at least not being flat.
This also prompted us to think about how and why things do not fall off a round-edged world into whatever is beyond the horizon. Perhaps everything is falling into the centre – gravity. Eureka! All problems solved.
The fact is we have observed, with our own eyes, the planets and planetary satellites out there, and they are not flat but round. Things don’t fall off the planets because they are round. And the Earth is not special. It is not flat. And we, human beings, are not special. The world neither figuratively nor literally revolve around us, just as the Sun does not revolve around the Earth. It is only ignorance and arrogance that makes us think the planet and us are special. And sometimes people are kept ignorant for reasons of maintaining this power and control over them. This is not unlike the flat-earthers’ narrative that the Sun revolves around the flat Earth, all the while telling you that you are their Sun.
