You're presupposing that we're moving in the first place, even though it cannot be observed or felt, buying into convoluted theories that it's relative from a guy who stole his "work" from other people. It's all just an "illusion" according to them.
It's all an amazingly fantastic idea that was placed in our heads and rationalised through years of programming, and I completely reject it. The only time we ever feel anything is when the earth moves beneath our feet via an earthquake or tremor. Everything is else theoretical bullshit that I no longer subscribe.
It cannot be felt but it can be observed.
We already went through this.
You're wasting your time here. I spent 38 years of my life believing in the same thing that you and most people continue to believe, and I'm done with that until some solid answers are provided. And these aren't the questions I'm asking. In fact, I'm not asking any questions here.
It's very simple. Let some flat earthers go to Antarctica and freely explore to put this all to bed. They will never allow that, so we're at an impasse of ideological beliefs.
Solid answer: Foucault Pendulum.
Conclusion: can be observed.
