The flat earth has never made sense to me. I do believe gravity exists but I have a theory that angels have something to do with it. They do have control over the celestial bodies and the heavens. It's essentially the force that causes stuff to fall, in order to move something, it needs propellant or a driving force, gravity is the driving force that causes an object to propel downwards. Another thing is the international space station. Some of you will probably say "Oh, that's just a NASA lie. It doesn't exist". Well, it does and there is a site where you can track its movement. And it's gone over my house several times and you can see it with a telescope. Now this doesn't mean that I believe we went to the moon or the rover on mars, or the Heliocentric model. There are legitimate doubts for many of those topics.
