I kek that the "Earth is flat" meme can EASILY be disproved by a few simple things: 1- Literally just RECORD THE SKY WITH A FUCKING PHONE. Put a fucking camera in the sky pointed to Polaris, you'll see that the movement of the stars is like if you were on a globe. Then go to South America and do the same there, so you can see the bottom part of the rotation. Also you can't see all stars at the same time, but you can put the video from the North with the one from the South and "glue" them by matching the stars. BAM, you're in a globe. 2- Seasons of the year. The only logical way that the seasons exist the way the do (inverted in North and South) is by having a shifted globe around a star. 3- Measuring shadows in two different places at the same time and triangulating the difference in degrees, people did that thousands of years ago.
