I know it isn’t a popular opinion here, but there are a couple things you can do pretty easily to prove to yourself the earth is either flat, or a lot bigger than they told us. The math they have provided to calculate the curvature of the earth doesn’t hold up when you have a camera with a powerful zooming optic on it. You can literally watch the sun set and supposedly go over the horizon, and then use a zoom camera to zoom in on where the sun disappears over the horizon, and the sun will come back into plain view. Test it out for yourselves. I don’t actually know if we live on a flat plane, but I do know that they lied about the nature of our reality.
