Ok let me clarify so we can avoid the rhetorical questions rigmarole.
If the earth is a 30km sphere as per the FE model (as I understand it), and its light path passes through the projected area of a 9km mountain, then regardless of the distance of the mountain, it is going to have a palpable effect on the quantity of light reaching the observer, ranging from 0% if you are standing in front of the mountain, to something in the order of 70% at the limit where both the mountain and sun are at an infinite distance - I get that number from approximating the relative projection area of the mountain to a 30km sphere projection.
Assuming you don't believe the sun is a 30km sphere, and is rather a massive light source (commonly known to be composed of a quark gluon plasma) at an optically infinite distance, then you would expect the light reaching the observer to range from 0% directly in front of the observer, asymptoting to 100% at the limit where the moon and comparatively infinitely large sun are at an infinite distance from the observer.
I am of course making the assumption here that the FE model uses the 30km sun sphere.
