I have seen it. The only reason you have not seen it is because you have not studied the sky carefully enough.
James, you are IGNORING the FACT that the people who study the sky most carefully - professional and amateur astronomers, William Herschel, Patrick Moore, Clyde Tombaugh, David Malin and countless others - not a single one of these has EVER reported seeing anything resembling this object, yet they managed to pick out tiny, dim objects invisible to the naked eye such as several hundred asteroids, Pluto, Eris and so on. Yet they all miss, without exception, a black disc the size of the Moon blotting out the stars as it travels across the sky.
You'd make me laugh if I didn't worry you really believed your own tales.
