You could say that the earth is not spinning but everything is moving around the earth.
True formulas might now work but if we have no agreed upon center, how do we know we are the ones spinning?
Are you just playing devil's advocate or do you really have doubts Earth spins? There are so many lines of evidence Earth spins, you can just google earth spins. For one thing, you weigh slightly less on the equator than you do at the poles, for two reasons, one of which is a direct result of the spin, in that it bulges measurably at the equator so if you had a yardstick long enough if you drill a hole pole to pole it would measure a few miles shorter than drilling a hole from equator to the opposite side of Earth. So at the poles gravity is a bit stronger than at the equator, and that changes the apparent weight so that on a non-spinning Earth you would weigh slighly more than at the equator, since gravity follows the inverse square law but that is counterbalanced by the fact Earth spins and someone at the equator tends to get flung off into space. That doesn't happen because gravity way overcomes that effect but both effects can and has been measured many times.
Of course, if you are aligned with Freaky, you are in the non spinning Earth and would be a flatassser. Do you think Earth is flat and non-spinning? What leads you to this conclusion? Are you just parroting other people or do you have actual thoughts of your own on the subject? The bit about Coriolis not being true because you can't see a toilet flush spin in one direction is bogus because it effects large scale air movements and ocean currents. Also, it is well known if you shoot a rifle, a long range rifle, you better have a good handle on coriolis, the spin of Earth effects the apparent path the bullet takes over the ground, there is a big difference in a bullet shooting say 45 degrees to the right of north vs shooting the same rifle 45 degrees to the left of north, the same load of bullet and powder will put the bullets on a different path if not taken into account.
Plus the Foucault Pendulum swings around 360 degrees every day, you would have to explain how that can happen on a non-spinning Earth and the gyroscope experiments that show the angle of the rotating shaft changing 90 degrees in 6 hours if the shaft is pointed east-west but not if the shaft is pointed north-south.
There is no non-spinning Earth rational that can explain all those phenomena.
Also, I calculated how far away from Earth you would have to go to get the stuff spinning around a non-spinning Earth and at around 80 billion Km anything there would be spinning at the speed of light and of course at 800 billion Km, it would be spinning around ten times the speed of light, and that is just the close stuff astronomically, the nearest star would be spinning around Earth about 500 times the speed of light. That is just the closest one at 4 odd light years away, Alpha Centauri. Try to rationalize all that.
