This simple concept occurred to me when I was like 12 years old, and from then on, I've always known flat earth was bullshit. I think flat earthers are just bad at this kind of geometric thinking, and none of them actually have an interest in stargazing or astronomy, so they don't even know that this is a thing. Astronomers and have known for millennia that the earth is round because they paid attention to the sky

You are retarded. Capturing the rotating night sky is like babby's first astrophotography project.
