Based on the size of the planet and our own minuscule size over it, the tinny part we can see will always looks flat, no matter if Earth is flat or oblate spherical, also, the bottom of the clouds are flat since they are literally SIT over a cushion of warm atmosphere, it is like foam floating over water, and that, would not differ from happen on Flat Earth or oblate spherical one. The FE statement about this is the same as saying: "Oh, this car runs on gasoline, using an Otto engine, over four rubber tires, so for unquestionable truth, it is a Ford". I would like to read how a FET believe the bottom of clouds should be on a RE.... round?
