This is why saying, "The earth is not moving because we cannot feel it moving" doesn't work.
You would be using the earth as a frame of reference to describe it's own movement.
It's circular reasoning, and confirmation bias to say that, "because we on the earth cannot feel it moving, therefore it does not move," because by definition, we are fixed to that which we are trying to describe the motion of.
There's no external frame of reference by which to define movement, therefore ascertaining whether the earth is moving using only a point on the earth's surface is impossible.
Again, by definition, all objects are motionless relative to themselves, but not to other objects (external F.O.R.).
An earth that was spinning at the surface 1000 to 600 mph would be impossible for us to live on.
There is no need of a reference point at that speed.
