Sometime in 2015 I started seeing references to flat earth and noticed Obama kept mentioning it, so I looked into it to try to figure out why. I learned enough to know flat earthers don’t accept those photos of earth from space as real. Apparently NASA has admitted they are “composites” which provided an opening for them to be discounted completely. I say “apparently” because that’s what leading flat earthers say. I have no idea what NASA has actually said.
If the earth is flat, how can someone sail around the world without falling off?
