You have to decide for yourself whether you want to believe the moon is a physical object floating above your head or whether it is holographic projection.
If you can understand how a rainbow is not a physical object, then you can begin to consider that the moon is just a reflection of light/energy emitted by the earth.
The wiki makes the assumption that the moon is a physical object. There is no proof of such and the appearance of the moon lends itself to being a projection.
The phases you see of the moon projection are easy to understand by experiment.
Take a
glass cake cover and shine a torch light down through it in the dark. You will see the same moon phase projection as the focus of your light moves in and out from the center of your dome.
