15We Wouldn't Have Mountains
This one is rather straightforward. If Earth were actually flat, there wouldn't be mountain ranges, or hills, nor any naturally occurring formations spherical in nature. Therefore, if you enjoy mountain climbing, nature hikes, or even enjoy looking at the various peaks and valleys around the world - be extremely grateful
that the world isn't flat.
If our planet were to somehow transform to a flat surface overnight, all the mountains would disappear. It's that simple, everyone; the mere existence of mountains proves this globe (get it?) we live on is indeed not flat.
