Do you question globe while blindly believe in flat, against observations and measurements?
No.
Ok. Thanks.
Now, let's try this thing together:
Does Sun shine in every direction, regardless the model?
Let's not. <--- fear of facts 
I don't know what kind of bizarre protracted Socratic dialogue you feel compelled to try to draw me into, but I don't have the patience with you to play this kind of game.
Your OP fabricated a model and then discredited it.
That's called using a straw man.
I called you out for using a straw man.
Don't use straw man arguments. They are logical fallacies.
For each of the three models I clearly said "THIS ONE IS NOT how it might work".
And I asked anyone to replace any or all of the three non-working models with the working one.
Could there be such model? How would it look like?Could you even force one?
Sunlight can either be directed or not (Sun can shine in all directions, or in cone shaped area).
Sunlight can either have unlimited reach, or limited (if limited, we can calculate where is the limit).
So, how many combnations there is?
Can we have unlimited number of combinations from limited number of elements?
In addition, if the sunlight is cone-shaped, it obviously becomes irrelevant if the reach of sun rays is limited or not.

Speaking of your way of using the phrase "Socratic dialogue", you apparently don't even understand what was the essence of his dialogues, and why was he killed.
