Flat Earthers often make the error of trying to fit one observation at a time into some distorted model of the Earth and then starting over with the next one and making up something else to explain it. None of it fits together and they do not have any actual mathematically accurate model - AT ALL.
Here are just a few of the observational facts that must be accurately accounted for in your "theory" - which I will happily review once you get it published in a reputable, peer-reviewed journal…
The tidal bulge on the Earth is not towards the moon, and not lagging behind the moon, but is out in FRONT of the moon [the moon pulls the mass of the Ocean towards it but the Earth rotates this bulge out ahead of the orbit of the moon - this gravitational bump ALSO pulls the moon towards this greater mass, accelerating the moon ever-so-slightly and causing it to move slightly, but measurably with modern technology, further away from the Earth].

The annual and diurnal aberration of starlight
Parallax measurements to nearby stars (combined with aberration measurements in phase)
The phase resonance of Earth-Moon due to Tidal locking
The daily apparent motion of the moon going completely around the Earth despite it having 2,413,000,000 meters to go which takes ~28 days
The motion of a Foucault pendulum which varies by latitude
Earth-Moon, Earth-Sun barycentre measurements
The Lagrangian point(s)
Precession of the Equinoxes and ecliptic
Apparent motions of the distant stars (combined with parallax measurements which measure their distance)
Apparent motions of the planets, comets, asteroids, etc
All of these facts are accounted for with the modern heliocentric model (relativistic) to many decimal places of accuracy based on one simple principle of mutual gravitation of mass and do not require distant galaxies to move at trillions of times the speed of light around us or other absurdities that result from myopic Flat Earther claims.
