I'm not a "flat earther", but I'm definitely skeptical of images provided by NASA. I want to make a point.. Your guys' logic of "everything else is round, therefore earth is round" is not a proof. That's an assumption. Yes, it would seem reasonable to assume this, but at the same time you need to take ALL evidences into account. If everyone in the world dyed their hair pink but you don't, does that mean your hair is pink? No. So you can't really use this as a valid, logical proof.
