You can ignore me if it pleases you, but your argument for sinking ship is flawed. You stated that if human vision is limited how come we can see the distant stars? We argue for the flat earth model, and in a flat earth model the stars are close to the earth they are not millions of years away, by this model your argument is irrelevant. In a flat earth model if you stand on the beach and you watch the ships drift further away, eventually they get far enough and you loose sight of them, this does not prove that the earth is round, it proves that our eye sight is limited.
As far as astronomy goes, its a waste of tax payer's dollars. They haven't made one discovery that they were able to prove. In a round earth model the stars are suns, and even astronomers agree that all these suns are very different from each other, some stars are red, blue, yellow, they vary in size as well. So if this is the case then why do they all appear to look the same in the night sky? Surely each star must look different to even our naked eye, since their properties are different. So right there astronomers completely fail to explain this. They say those suns all very diverse in their composition yet from the earth they all look the same, this is a major flaw in logic and common sense. Flat earth theory explains a lot more reasonably the true reality of what stars really are.
