Is this scheme the proper explanation of why the upper part of the moon is illuminated ?

That said, I will note:

You need to provide your own explanation in your own words, or I will shut down this thread.
We are not here to “justify” anything to you. You need to make a coherent argument to be debated or you are in the wrong forum–and possibly the wrong message board.

I will further note that you took a rather insulting tone with your correspondents in the one MPSIMS thread where I watched you play. I am letting you know that if you continue to insult other posters, you will jeopardize your posting privileges, here.
