Even though you reject the idea of a flat earth—which is obviously your choice—I’d still suggest watching a few videos on YouTube that explain how the flat earth model works. I don’t think you're fully grasping the perspective that the model presents. For example, the sun doesn’t "set" in the way we've been taught—it moves further away. It's also not as big or distant as mainstream science claims.
I’d also like to offer a bit of advice when it comes to researching anything, whether it's spiritual matters, health, politics, or even topics like the flat earth. What has really helped me is this: try to prove yourself wrong. If your belief or theory is true, then you shouldn't be able to disprove it. This approach helps keep your mind open and grounded.
So in this case, try to prove that the earth is flat. Go against your current thinking and see what you find. One way or another, you’ll come out more solid in your conclusion—whether you end up confirming or rejecting it.
I try to prove myself wrong all the time. It’s how I stay balanced. Hopefully, this didn’t go over your head.
