My question is:
How is it possible to see further when you are higher up when stood on a flat earth.
Because the higher up you go, the further away you can see before the horizon comes up to you eye level.
Now if you were really standing on a globe, you would automatically be at its highest point since a spherical surface would bend down away from you in all directions. As you rise in altitude, the horizon
should get lower and lower, because you are now rising above the sphere. You should also see the distant land bending down away from you more and more radically the higher you rise. Yet this is not what you see.
Since the earth is a flat, extended plane, you see further and further away until the horizon
rises to meet your eyes. Whether you are 100m or 500m or even a few kilometers up in the air, you will
not perceive the horizon getting lower and lower, as it should, and this can plainly be seen by looking out any plane window. This is proof that the earth is a flat plane and not a globular surface bending away from you.
