No Way The Earth Is Flat 4, Are we that special?

We look up the sky, we see all the stars, planets and moons. They all have one thing in common, being round. Does appearing round to us necessary mean they are in a sphere form. Well, unless they are all placed perfectly with the round side facing us, otherwise the only other explanation for this phenomenon is that they are in sphere form. But can we prove it? Of course we can. And we don't need the lying NASA to do this for us. In fact, it is really simple. Just look at the moon. The moon is a sphere, because it is like any other 3-D object, it has a bright side and a dark side when being shined on. And the constantly moving moon against the bright sun shows all angles of the sphere shape of itself. Any human eye can easily tell it's a sphere by looking at it. And if you have a telescope, you can also see the same phenomenon on other planets such as Mars or even moons of Jupiter. They are all spheres. None of them are flat. In fact, you just can't find any single large object in the sky that is flat. Oh no, someone did find something in the Cosmo that is flat, galaxies! But hey, that is not "A" thing. It is a group of things. It is formed by billions of star systems. We are talking just one single object here. None of a single sky body we see in the sky is flat. So why would we assume we live on such a world. Trillions and trillions of Worlds out there, we are the only one being flat? One against trillions of trillions? We should stop thinking so big of ourselves already. Be humble, accept we are part of the Cosmo and be in harmony with everything else besides our ego.
