Lunar eclipses are caused by a celestial body intersecting the path of light between the sun and moon, as is physically observed.
Your very own photograph shows a story that is different from yours. The penumbra that your photograph shows is totally inconsistent with an object intersecting the path of light between the Sun and the Moon just 3000 miles above us.
If the Moon produces its own light then parts of the Moon will be covered by the dark object and others will not be. No penumbra. And if the Sun somehow illuminates the Moon then it will also illuminate the dark object, making it visible. You have been asked for a diagram for many years, as far as I have seen, but never have produced it. I think it is just impossible to do because it is impossible to make your scenario work.
By the way, it would be absolutely easy to see almost any night the effect of a dark object the size of the Moon. On a clear night far away from light pollution from the cities it is impossible to find any dark, star-less piece of sky the size of the Moon. It would have to be made of a magic substance that is perfectly transparent to star light but perfectly opaque to moonlight. And we know, because we have centuries of experience in the matter, this kind of substance is impossible.
