The Earth is not flat. However, many anons will inevitably notice that NASA doctors every single photo they release. Some are glaringly obvious, while others are very subtle and some are so well-done you have no way of knowing they're doctored because you've never actually seen the areas represented in those images.
Why, then? We already know the Earth is not flat, so why modify every single image they release?
Easy. It's because there are several surface settlements and installations that no one is supposed to know about. NASA obscures these in various ways. There are some in the Southwest U.S. deserts, some in Antarctica, several in northern central Canada, and various others in places I'm not aware of. These serve as retreats and manufacturing bases for the globalist elite.
