All right. Well it certainly felt like you were implying that I had "use[d] the claim that we lack the technology to see far enough to prove the earth is flat." If you feel I made that claim could you point out where? Or do you just make random statements like that periodically.
The entire premise of your argument in this thread tries to split hairs on our ability to use advanced optics to see distant objects under certain conditions. The fact is that when an object moves far enough away in relation to the perspective that it is being observed, it can move to a position where it can no longer be observed specifically due to the curvature of the earth (see: line of sight). That being said, we have the optical technology to see far enough to prove the curvature of the earth, yet you continue with this example of a ship knowing full well it is a bogus example and has been debunked with facts that you can observe for yourself. To try and press false information as evidence to support a point you know is wrong, is called lying. Unless you are in fact just delusional and have no idea what you are doing.
The instances where the ship was not restorable was addressed as well. See the chapter Perspective at Sea in Earth Not a Globe.
You assume that just because people disagree, they are unaware of the information. Just because the issue was "addressed" doesn't mean any of it is even remotely true. And by the rules of your empirical beliefs, you have to assume this is all false since you yourself have never seen it anyways.
You will lose 100% of the time when you try to argue perception against fact (whether you admit it to yourself or not).
