They wouldn't necessarily notice anything different, and if they find anomalies, they go for the round earth explanations. But there are some who are noticing strange things like UFOs.
That answer makes absolutely no sense.
Do you even understand how many amateur astronomers are there? From different countries, cultures, backgrounds and religions? Do you understand this? Do you have any concept of what that means? Not a single on of them is discussing the "anomalies" they observe, asking about them, discussing them online and among themselves, making publications about them, etc? They are all magically brainwashed, somehow, regardless of where they are, who they are, or what their background is.
Your other answers are equally stupid, so I'm not even bothering to answer them.
I really, really hope you are just a poe. Else I have to question your sanity.
