You make like: "The Earth is ROUND or everything else is is wrong," yet I am the one one with the case of projection...
Sorry dude...
You still do not understand.
What I said is true, and a lot of Flat Earthers agree as well.
If the Earth is Flat, then Newtons theory of gravity has to be completely wrong. Einstein has to be completely wrong. Electromagnetic theories of light and radio have to be wrong. All of astronomy has to be wrong. Anything to do with mapping the earth has to be wrong. Geology has to be wrong. Migration of birds across the globe has to be wrong.
So yes, if the earth is not ROUND than almost all of science has to be wrong.
Now, you can still believe it's flat, but you have to reject all of science too. There is no "Round Earth Theory" you can just simply reject.
It's like saying math is right EXCEPT that 5+5 is actually 11. If you reject the roundness of the earth, you have to reject everything that points to it. Which is everything.
