Is there any satellite imagery of Earth’s poles or even Earth at all? Of course there is imagery of the poles and the earth as a whole. You must know that. No, the earth is not flat.
But it matters not because no matter what I tell you or show you, you will still go on believing the world is flat and NASA is involved in a giant conspiracy. I don’t even know why you ask these questions. You don’t want to hear why your narrow minded ideas are not accepted by anyone except a small group of kooks.
