I already covered that above. The stars are in the same galaxy as us. Whatever expansion is occurring they are on the same path as us - relatively speaking of course. The stars move throughout the night - is that what you’re claiming is a lie? If not, why do they move using your flat earth model? Are we just pretending you didn’t make a very obviously false claim about the horizon remaining constant in spite of changes in altitude? I was kind of looking forward to you trying to defend that.
