Earth's magnetic barrier is what provides us the shield against sun's rays, by diffusing them in a way, to cancel them out. The ionosphere is the thick layer where such collisions occur, the result being the ions produced from the diffusion of sunrays. In the Northern and Sourthern hemisphere extremities, where the magnetosphere is weakest, we have the Aurora effect. So we have an electrifying effect on the ionosphere and this phenomena produces a potentiona, difference between earth and the iniosigere, which evaporates sea water and produces clouds and rain. On a flat planer and non rotational and non electromagnetic earth model, there will be no weather effects and this planet will be a piece of charcoal wafer.
Our electromagnetic shield protects us from sunrays and produces our ecosystem for habitation. Without our ionosphere we would be a red smeltering charcoal wafer, like a burnt steak in a barbecue.
In addition, we are purposely located in a pot hole, called a gravitational vortex, which is really a stretching of the fabric of space and time. Our reality is relative to the gravitational vortex that earth is purposely by design, out there by God, so that every object on earth has gravity acting upon it approximately equally, with slight variations at the poles, which actually maps that we are in a space time slip, a stretched fabric in time and space. Our moon is also trapped in its own pot hole by design and it does not rotate and has no ionosphere and no magnetic shield and for that matter, it exposes the countless barrage of meteor strikes and its lifeless environment.
If we go to say another gravitational vortex like Jupiter, its effects are much stronger and it's squared effect means that it's observer based time reality is vastly different. So if you spent time on Jupiter let's say, within its gravitational vortex, you would get a time lagging effect which is to the power of minus three times that of earth. This means that ten days in Jupiter's gravitational vortex would be like 1000 days on earth. So as distant observers on earth, we see things almost instantanouesly happen on this planet, like pure magic, when in fact we are missing information because we are in fast motion and our time based reality doesn't pick up the transitions, but only the result. The slowed down reality of Jupiter is beyond our information gathering. Asteroids colliding with Jupiter are seen as an after effect, but their trajectories cannot be time linearly followed, there is a slowing effect to receive information, even though Jupiter has gravity almost three times greater than earth.
Flat earth wafer model is a medieval belief that doesn't even fit with scripture, as all things in our reality has the signature of God and is a spiral shape, like the Fibbonacci spiral pattern, from our revolving planet, to revolving gravitational vortex and revolving galaxies.
