It’s obviously round first piece of evidence is the countless accounts of people in space stating it is round, and you’ve got to think about it. Why would they lie and create this international conspiracy? What would be the point in saying the earth is round when it’s flat? Furthermore, second piece of evidence is that you can see the curvature of the earth from an airplane, if you go into the cockpit of a commercial airplane when at a cruising altitude of around 40,000feet you can see the curvature! So it wouldn’t just be people who have been In space lying it would be countless pilots, videos, photographic evidence falsified and for what?!
Overall, the earth is round.
