A person, "if the moon is a sphere lit by the sun", will see light emitting from all around the moon, regardless of the moons position. Because there is always an area of the moon in the full moon phase
The illustration show this. all the black dots on the shadow side will see light from all around the moon.
But in real life that is not seen showing that the moon 1. is not a sphere and 2, the moon is not lit by the sun.

The illustration you posted previously (and by the way it is also a poor illustration – how can the sky be dark in the daytime except by an eclipse??) which is supposed to be showing what the new moon should look like can only happen at a partial or total solar eclipse because at least part of the sun is being covered by the moon and the sun’s actual light becomes visible from
behind the moon. It is not the moon’s surface shining! This is an example of what it looks like:
What you are claiming should happen even at non-eclipse new moons can only happen if the moon tracks across the sun with respect to the earth, not above or below it. And again it is not the moon’s surface shining but sunlight appearing from behind the moon.
At a non-eclipse new moon the sun is not behind the moon but either above or below it. And so the moon will not have any sunlight appearing around its edge except the tiny sliver visible from earth on which the sun does actually shine and then it will be visible only with specialised equipment.
Here is a link to a website displaying a photo taken at the very minute of a (non-eclipse) new moon. I’m not going to post the photo here as the site requires prior permission if it’s to be used for anything other than strictly private purposes but the photo is the first one on the webpage.
Thierry Legault - World record : the youngest New Moon - July 8 2013
The site warns ‘
Caution ! The very thin crescent of the New Moon cannot be observed visually whatever the instrument (naked eye, binoculars, telescope...). Moreover, pointing a celestial object that close to the Sun is dangerous for the observer and his equipment if it is not performed under the control of an experienced astronomer and with the proper equipment.’
The equipment used was… ‘
Takahashi FSQ-106ED with focal reducer (D=106mm, F=400mm) on Losmandy Titan German equatorial mount, IDS 3370 monochrome camera (CMOSIS 2048x2048 sensor), low-pass infrared filter 850nm. Processing: combination of 4000 calibrated (flat-field) images, gradient removal by wavelets, contrast/brightness, colorization. The Moon has been pointed with the help of the GOTO system of the mount and tracked at the precise lunar speed calculated for the instant of shooting.’
The point here is that visually the sun was located at about 5° directly above the moon in the sky at the time of the photo and so the only visible part of the moon was a tiny sliver at its top and then only with specialised equipment. There is no reason whatsoever that, from earth, any other part of the moon should have been seen to be lit by the sun’s light if the moon is a sphere lit by the sun at the new moon phase, simply because
the sun’s light was not shining anywhere else on the moon’s surface that was visible from earth.
But if the moon is
self-luminous,
all of its surface facing the earth should have been lit and visible with this same equipment. It wasn’t.
Again I ask please explain how a self-luminous moon exhibits phases. And again, what Bible verses
define the moon as self-luminous?
