3) The ebb and neap of the Moon's elliptical orbit is not sufficient enough to effect this. This point is also mute because the Earth's orbit is elliptical to the Sun as well.

I think the key word here is "nocturnal." I'm guessing that if I saw the moon out faintly during the day, I could block it out with an extended index finger. And maybe, if it were possible for the Sun to be out while it was dark out, I might not be able to block it out with that same extended finger.
I'm guessing it has to do with the amount of light in the sky at a given time...either that or the fact that one is a source, and the other is a reflection...:whatthe:
