Please pardon me for being simple, and starting over with my "stick man" representation here. I know it's not to scale I'm just trying to maybe ask my question with a picture, since words are not always as clear and/or can cause unnecessary sticking points.

I'm showing the earth looking up from the south simply because we're all used to seeing west and east in the left and right positions. I am in the US so that is why it is on top. You should be able to get a reference as to where everything is from this pic. The moon is represented as full, because it is usually full or a large portion of the moon is visible when I notice it in the daytime sky.

What I've seen from the western part of the US is the moon in the west and the sun in the east. This is visible pretty much from sun up until around 8 am in the spring. (most recent recollection, and actually I can't say how much longer than that simply because I work indoors and cannot watch the movement.) Both the sun and moon were pretty good sized so they were closer rather than farther away.

So, my question is, how can any place below the line see the moon in their night sky when it's in the daytime sky in the area above the line?

Please answer using representations like this simple one, with whatever shape you think the earth may be. What's visible or not visible on a globe is not well explained on a flat representation. unless you're saying it's flat, but I don't think you are. In checking the premise, if it's not a ball and we've misunderstood, than what is it? Neil deGrasse Tyson's oblate spheroid has pretty much the same problem with this question of moon visibility.

Thanks
