Don’t be silly. The moon is a secondary reflection of the sun, which is produced by a carbon arc and crystal projector. Now I know that a dome had never been produced that can have a circle projected on it and produce another clear circle elsewhere, but superfluid helium domes can right. Now the really clever thing about this secondary reflection is that sometimes it is not even another circle, but a crescent, which appears in a totally predictable way.
The secondary reflection seems to move independently, appearing at different distances to the sun over the course of a month.
Now to observers with a telescope they can see what look exactly like craters. Now these patterns are completely different to the sun spots which don’t appear on the secondary reflection at all. And if you watch those craters over the course of a few hours and especially days, you see shadows change in a way exactly consistent with mountains and crater walls on a ball of rock, but that is just brainwashing kicking in.
A lunar eclipse might look like a shadow across the moon and seem impossible, but refraction.
It is predicted using magical maths because it just happens to fit.
All make sense?
No, try some paint thinners and have another read.
